Wikipedia's definition of a paraprosdokian is "a figure of speech in which the latter part of a sentence or phrase is surprising or unexpected in a way that causes the reader or listener to reframe or reinterpret the first part. It is frequently used for humorous or dramatic effect, sometimes producing an anticlimax." Paraprosdokians that I like are "I haven't slept for ten days, because that would be too long," said by the late Mitch Hedburg, and "I can't wait to get to home with my girlfriend, because my mom's making cookies." What are other paraprosdokians you have heard?
