Groan Tube Puns

We were talking about her cat and it went something like this:

Me: Is your cat spayed?
Her: Yep, poor Tubbie (the cat's name) has no uterus.
Me: Really? I thought they would have just tied her tubes instead of giving her a full "Hiss-terectomy"
Her: Groans for days

I am not yet a dad but one day I think I'll be decent at it.

At work we we have a large fireplace we use to heat the shop in the winter. Occasionally a sign shop down the street gives us some long cardboard tubes (think toilet paper but longer and thicker) that we can burn. It's a win-win situation that gets rid of their garbage and provides us heat for the winter.

Anyways I pick up the tubes and come pulling in the shop with a truck bed full. I start unloading when my boss comes up to help out. Upon seeing the tubes he makes the shaka sign (surfer hand symbol with thumb and pinky out) and says "Tubular".

I physically groaned at this one.
