Ayep. Bart was suspected of having called in a mob hit on Principal Skinner, but turns out he'd just been trapped under a ton of newspapers in his garage, only to eventually free himself in a MacGuyver-esque fashion.
sounds like my old upstairs neighbor in Philly. I used to stop by every now and then, and there'd be a shuffling noise as he moved things out of the way so he could open the door... then he'd clear a space on the couch for me, and a space on the coffee table for a beer and an ashtray... I always loved that guy, but I worried that someday he wouldn't be able to get the door open.
