The right bra size.
 

A guy had a T-gurl for a girlfriend. He wanted to get her a nice sexy gift so he went to a lingerie~ store. He talked with the clerk about what to buy. They decided a nice sexy bra would be nice. The conversation went next to determine what size might be appropriate.
"How big is she?" the clerk asked; not knowing this was a T-gurl.
"Well, I'm not sure", he replied.
"Is she as big as a grapefruit?"
"No, not that big."
" As big as an orange?" asked the clerk.
"No, I don't think so."
" What about a lemon? Is she as big as a lemon?"
"Not that big, smaller."
"Okay, is she as big as an egg?"
"Yes, that would be about right. As big as an egg; two fried eggs ! "

Hilarious!!
