A casual joke... Student A: "Why did the baby cry?" Teacher: "I don't know, why did the baby cry?" A: "No, you have to guess." T: "Because it was sad." A: "No because the dog barked at it." Student B: "That's not a..." A: "Sure, sure, sure, sure" *while waving off Student B's comment*
Student: " Want to hear a long joke?" ... Student: "Joooooooooooooooooooooooooke."
Overheard at the Store
Clerk: “How do you pronounce your name?” Me: “uh-lee-tha” Clerk: “Was your mom biting her tongue?”

            -Clerk after seeing the name on my credit card.

  It took me a long minute to figure out it was a similar question to one someone else had asked me a few years ago:
“Do you have a lisp?”
While reading "Sarah, Plain and Tall"...
Me: "He ordered his wife in a newspaper!" ... Student: "You should do that for your husband!"
"Do you know why some people have hair and others don't?" ... "The people that don't have any hair have perfect heads, everyone else had to cover theirs up with hair."

-Our school counselor, who happens to be missing a little bit of hair on top.

"Can you tear it out? I'm TEARible."

-pun itself was pointed out by another student who heard the question

"What is my favorite farm animal?" ... "Fried Chicken."
