Know any good (bad) puns?

Puns have been described as the lowest form of humor, maybe because they are language specific. I don’t care what anybody says. I have a weakness for them and word play in general. I just came across a recreational math book with a beaut of a title, Here’s Looking at Euclid. Do you have any favorite puns to share?

In case you did not care for the book title, I present to you the amazing triple pun. A cattle rancher leaves his property to his sons. Since the enterprise was never given a name, they decide that coming up with a name should be the first order of business. They choose to name the ranch Focus, because that is where the sun’s rays meet.
