My grandaughter made up a knock knock joke

[MamaMia]

She said, "Nana, knock knock."
I said "Whos there?"
She said "O-S."
I said "O S who?"
She just giggled. :P

Spek to the granddaughter!

Well, until she gets her degree from OU, she can't be a fan.

Keep that in mind.

Remember, she has to know about every crack and leak found on the campus's old buildings, too.
