Things that make you go hmmmm

I had an unexpected stay at New Guy’s. I had my bathing suit on under my clothes and was kind of stressed about what I would sleep in. Call me crazy, but I have to be pass-out drunk to sleep naked. I like something between my cooter and the sheets. So, he tells me not to worry - he has a pair of underwear for me…

Then he pulls these out:

"They were a gag gift," he says.

Ummm…?

My mind starts racing about all the possible inside jokes that could be at the root of this gag:

Did some ex-girlfriend think he laid pipe like Clark Kent?
Did some chick tell him he threw her around like Super Man?
Had some woman finally figured out his kryptonite?

Like I said, call me crazy. Girlfriend needs to get out of her head. One thing I know for sure, his ass was never in these things. They were snug as a bug on me.

But seriously…why does he have Super Man undies?
