Different Breeds Of Humor

I have just started the training for my current job. For reasons I can’t remember, our teacher chose to inform us that he and his wife had chosen not to procreate by saying:

Teacher: “All my children have four legs and tails.”

I have no idea where it came from, but I spat out without stopping to think:

Me: “Jesus, I’d hate to see what your wife looks like.”

My class burst out laughing, teacher included. He went a little hard on me the next couple of days, but was a good sport in general. We had a lot of fun in that class, and a big part of that was all the s***-slinging.
