That's a tough one because I have a number of favorite Regular Show episodes..but my favorite episode right now is "This is my Jam" and my favorite part of it was when Mordecai asked Pops to dance to the Summertime Song and Pops replied He couldn't stand that song and he eventually said "But I'm Not Going to use my best dance moves!" I loved that XD
My fav episode has to be the karoke episode and my fav part of tht episode is wen everybody at the club is fighting and pops is singing footlose in the background its great watch it on utube on demand or somthing its great XD
