Three Sixes???? 666??? medicine?

Craziness in the pharmacy again. These older african american ladies steped up to the counter the other day and asked for some help.

"Excuse me do you have any other types of the three sixes?"

"No, I've never heard of it, I'm sorry." I reply.

This is where it gets fun...

"You don't know about three sixes medication?"
"Yo daddy knew about three sixes. I want the three sixes with quinine. It'll fix anything."

"I'm sorry we don't have anything like that." I try to say without laughing about 'yo daddy'.

"Oh well, where's your Geritol at?"
