Someone (I don't know who) gets fired from a cannon on the Krusty Show, crashes through (I think) Apu's Quik-E-Mart where he crashes through a stack of jars of acid on his way through, then crashes through a sandpaper factory, finally ending up in a pillow factory where he heaves a sigh of relief at a soft landing, only to have the building blown up!
Thanks, Nigel Aagh! Every time I learn something new... it pushes something old out of my brain!
