Watched the Lisa 'vegetarian' episode the other day with the cameo from Paul and Linda McCartney.
Didn't half crack me up at the end.
Paul: ''Lisa, before you go would you like to hear a song?''
Lisa: ''Wow! That'd be great!''
Paul: ''Ok, take it Apu''
Apu starts tapping on the bongo's and singing Sgt Peppers.
