I love south park I prefer the older ones though. My fav episode is hooked on monkey phonics season 3. That opening 3 minute sequence always has me in stitches even though it probably isn't lmfao funny. http://streamallthis.ch/watch/south-park/s03e13.html
Starving marvin season 1 is another classic one for me. http://streamallthis.ch/watch/south-park/s01e08.html
Any episode where Cartman gets pissed off is hysterical. South park is great to just take 20mins away from everything laugh a bit and as long as your not easily offended it is good fun.
