Yeah no shit... Imagine doing that one "technique" of crawling under the mattress (and onto the box-springs) and having someone walk in on you! LMFAO What kind of technique is THAT?!
"Uh, well, I was just trying to sleep without all the light in my eyes, so I crawled under the mattress, naked, with a fistful of tissues and my KY jelly-filled condom on my cock..."
ROFLMAO
