When Homer breaks his ankle playing basketball and tries to run away from the hospital without paying for his treatment (claiming that he saw a bear in the hospital). After taking one step, his ankle breaks again in an insanely painful fashion with a bone crunching sound effect. While he's in pain on the ground, a concerned bear walks over and scratches his head.

Postie 'Ok. Whats your first name Mr Burns?'
Homer 'I dont know...'
