Twisted 'Ren and Stimpy' creator John Kricfalusi animated the opening "coach gag" sequence on 'The Simpsons' last night, bestowing his distinctively grotesque style to Springfield's first family. 

Kricfalusi is the second guest animator to do a couch gag in the Simpsons' 23 season history -- the first was notorious graffiti artist Banksy, whose sequence ran last season.
