Fixed that for you. =)
(This was actually how I initially read that post, too. :D )

I'd go back in time and take a lot more pictures of my wife and kids...mostly the wife as she is camera shy when sober and has been pregnant or nursing off and on for over a decade now.

As for an actual lame use of the time machine. I would go back to my first day of college and tell myself which girls were interested in me, instead of you know telling myself to not drink so much and study a little.

Go back in time to a sporting event that you already know the outcome of, but not bet every cent that you have just watch it live.

Similarly, go back in time to a game that I went to just so I can see what happened while the real time version of myself was in the bathroom.

Not really a lame use, but a silly use, I would spend all day learning a form of martial arts, and reading a lot of knowledge books, at the end of the day I'd go back and read more and learn more, then repeat that day over and over until I knew a ton of shit and could teach Bruce Lee a thing or two..

He could have meant a message: "Your zipper is down".

Best one so far. +1 to you sir.

I don't know how that one would get resolved.

You'd pretty much ensure your own non-existence doing that (given how genetics actually work), but then if you don't exist, you can't go back from the future to do it and if you can't go back from the future to do it, then you exist again and if you exist again, then you can go back from the future and do it, but then you don't exist, ...

I think you just created a case of infinite recursion in my mind.

The problem with those time-travelling scenarios is that they can't really resolve unless you add additional theory that prevents whatever you are doing in the past from affecting you (like you going in the past forking a separate reality at this point in time that is distinct from the reality you came from).

I'm pretty sure he did mean "message"; but I initially thought he typed "massage", and I found it funny, hence my "FTFY" post. :)

Though traveling through time just to tell yourself "XYZ PDQ" would also be suitably lame. :D

Go back in time for the thrill of shouting out the surprise ending to a movie. (a friend of mine did this b/c he had a script before the movie was released in theaters -- not nice :D)

Going back in time to actually visit Stephen Hawking during his Time Traveler's luncheon which he pridefully and idiotically believed anyone would care about. If I had a time machine, I would not visit Stephen Hawking. He'd give away my secrets of time travel and my identity!

I would also go back in time to make sure my face was in several famous photographs, but somewhere in the background. And then whenever someone figured out that I was in all the photos, I'd go back in time and kill them. Then nobody would know it was me! Muhahahahahahahaha! I had to go look it up. Very fascinating!

It's sad that they mostly get sick and die or get eaten, though. It's like an elf dying in LotR. You just think, "Darn, what a waste!" even if they're 700 years old.

That is kinda what almost happens in "Back to the Future". :P A tea table (UK version).

Go back in time and get a deal on the dump ground where the E.T. The Extraterrestrial cartridges are going to be buried :D
Put them on auction afterwards.
Build a second time machine
Play tag in time with them
Find Carmen Sandiego.

Go back in time to sleep with your grandmother, ensuring you wont get alpha brainwaves, in order to save the world from space flying brains.

God, I miss Futurama.

Backing up a computer.

Owait, my computer is a Mac... nevermind.

Thanks for the idea.

Telling then-me the actual reason why I didn't get an image on my computer screen, so that I'd still have the screen today. I thought the screen was broken, but should have thought of checking the CMOS battery (19/20th-century macs wouldn't output an image if the CMOS battery was empty, and I regret throwing away that screen as it was perfectly designed for the machine I still have).

Perhaps I might even convince a friend to give me back a few bits of hardware I've given him through the years (before he lost or broke them).

Sneaking my gaming collection to PA. I had to give up my collection from NES to GCN.

Screw that - I've seen The Fly. YOU get in there.
