they just have to so they can still be friends for the next ep, cause if i had invited him over to stay at my place until he finds his own and he started bossing around his demanding lifestyle and forces me to accept his needs over mine he can go live on the street for all i care! i don't kow how they put up with that guy, must be the mil an ep they're making!
Except at the end he says "Hey guys, I'm sorry I know I wasn't the best guest. But just let me know when I'm bothering you and I'll cut it out."
Making fun of your friend behind his back and trying to talk him into moving into a shithole apartment without telling him "hey man, can you turn off the humidifier" is childish.
