I used to work in the men's furnishing dept. of my store...you know, underwear and suchlike.
One time, I got this prank (I hope) call...
Me: Hello, this is (Store Name, Department) How may I help you?
Caller: Do you sell silk thongs?
Me: Yes sir, we do. A brand called Mansilk (Yes, it really was...

)
Caller: Well, I am especially big, so I need to know how big the 'pouch' on the thong is...!

Me: Uh....well...I am not sure...

. Let me finish with my other customers, and I'll be right with you.
So, I actually went back to the couple I was really helping, and told them about the caller's request. The husband and wife laughed, and we all tried to figure out how you'd measure the pouch for a thong panty...
We finally figured out that you could ball up a sweat sock or two, and see how many would fit in it...I went to the phone to tell the customer my solution, but he was no longer there. Darn. I really wanted to know if he was a one or a two-sock man....
