Hello , I only know of "The Day the Earth Stood Stupid" episode but there is an episode entitled "Futurama: Bender's Big Score" where there's a 22 minute episode "Everybody Loves Hypnotoad"
"Bend Her" which was the 13th episode of the 4th season .That one was funny
there are 6 seasons of futurama and 4 movies... and george Lopez has 6 seasons as well. you can watch every episode of futurama on futuramaepisode.org
'Xmas Story' , with Robot Santa .
that is a matter of opinion but I'd say episode 84
