A duck walked into a pharmacy ...

That duck lost his medical license. He was a quack.

A penguin took his car into a repair shop for them to look over. The mechanic told him to come back in an hour so he went and got an ice cream cone which unbeknownst to him, got all over his beak. When he went back to the repair shop, the mechanic said "well, it looks like you blew a seal" and the penguins replied "No, it's just a little ice cream.".
