I like to wear t-shirts that say things like 'world's best grandpa'...
I'm clearly NOT a grandpa, or a grandma....but I like to go to the Salvation Army and find t-shirts that say things like 'World's Best Grandpa' or '#1 Grandma' or other such things. I like to wear them around, I think it's funny. I've never seen anyone else do this.
Also, if I ever happen to run into an actual grandma or grandpa wearing a shirt that says something similar, I'd act offended and challenge them to a contest to prove once and for all who's the best.
Is this normal?
