I thought one of the funniest episodes was the dentist. First, he changes his clothes in the car and brushes his teeth. Then, he spits out the toothpaste, which lands in some construction worker's ass crack. The worker touches the "spit," looks up at the sky (for any birds) and then sniffed it. Just priceless.
Then in the dentist, he uses the suction to vacuum lint off his suit and to suck up the dentist's apple juice. The dentist saw his juice was gone and gave Bean a dirty look and asked for more. Then Bean took the novacain needle and held it by his side so the dentist wouldn't see he took it. Then he accidentially stabbed the dentist with the needle and the dentist passes out. Then Bean proceeds to do the procedure himself. Just a very funny episode.
