A man with a pegleg, hook hand and an eyepatch went to apply to be a pirate.
Interviewer: How did you get that pegleg?

Pirate: Arrr. I got me leg shot off during the first world war.

Interviewer: How did you get that hook?

Pirate: I got me hand cut off by a big knife.

Interviewer: What about your eyepatch?

Pirate: It was a rainy afternoon and I looked up into the sky and a bird pooped in me eye.

Interviewer: And that put your eye out?

Pirate: No, it was the day after I got me hook.

A lecture about English
A linguistics professor was lecturing to his English class one day. "In English," he said, "A double negative forms a positive. In some languages, though, such as Russian, a double negative is still a negative. However, there is no language wherein a double positive can form a negative."

A voice from the back of the room piped up, "Yeah, right."
