My dog, Grandpa

The other day, my professor asked me what I'd name my dog if I got one.
I said, well I'd name him Grandpa.

That way, when people asked how my day was, I can say things like:

Oh man, I forgot to feed Grandpa today.

I feel bad for leaving Grandpa outside last night.

Grandpa pooped in the living room again.

I had to put grandpa down today.

Grandpa ran away again.

I caught Grandpa humping my friend's leg again.

And people who don't know me, won't know what I'm talking about.
