No need to worry, guys. Those people you see on those japanese TV shows are never "anonymous" guys, they are what we call here "tarento" ("talents"), actors who generally only show up on TV. Most of them are comics, too.
So, basically, they are paid to do things like that, to overreact, to fall, take bumps and so on, in a "slapstick movie" spirit. And believe me, on japanese TV, the more incredible, the better ! They also replace the candidates in shows like "who wants to be a millionaire", that's the way they earn their living!
On the second video, the very first guy you see is Hama-chan, a very well-known talent who host many shows as different as the one you see here and more regular talk-shows about sports, news, etc...
Don't forget that "Beat" Takeshi Kitano also did "Takeshi's castle", which is not the most subtile form of humor, while also hosting serious political debates.
That's how incomprehensible Japan can be sometimes (and this comes from a French guy living in Japan and loving it ! ;) )
Yes, it's very often tasteless to foreigners, but that's just how japanese humor can be, sometimes. Personnally I find it hilarious, but maybe it means that i stayed for too long in Japan... ;)
Oh, and about the laughs : they are generally as real as the ones you hear in Friends or The Big Bang Theory... ;)
