Explain the following joke?\nQ:What is a plumber’s favorite food? A:A leek!
Explanation:A plumber is a person who fixes water pipes if they are clogged or are dripping; that is, if they have a leak.
A leek (two e’s) is a vegetable a lot like a green onion. A leak (one e, one a) is what happens to the water pipes when water drips out.
This joke plays with the word leek/ leak and that is what makes it funny.
