Man, the 100% cotton Nintendo Mario & Luigi Sleep Pants are powerful...I touched them and I immediately yawned! Then again it may have been since I was up all night playing video games and seeing these soft sleep pants and their mustachioed plumbers made me think of Little Nemo's Dreamland. Not the action of sleeping...the old school video game game! You see where my mind is, right? I'm sure you know what I'm talking about and already want the drawstring Nintendo Mario & Luigi Sleep Pants. Yeah!
