ok first i have to say this... my mom is a psycho-on-weed type of mom... like the mere mention of weed and she'll be bitching for hours.. anytime she sees anyone of us (me my brother, my wife, all her husbands kids, and so on) being secretive to each other she automaticly suspects it's weed..

ok so we had to go to my mom's for a month or so when hurricane rita hit, me and my wife were sleeping on my brothers bed, he was sleeping on our cot (he had a bigger bed then we did so we switched) well all our stuff was in his closet too, which the cot was right in front of, so my wife needed something.. she decided to look into a hole in the door to see if he was awake, cuz if he wasn't there was no sense in going in there as she couldnt' get to what she needed anyways.... well i see her covering her mouth, face red as hell, like she's about to explode, she manages to run to the living room before letting it out... she whispers to me in front of my mom (big mistake) of what she saw... "i was going to get <insertitem> and i decided to peek in to see if <brothersname> was up yet so i could get it, well i look in and i see him, awake, with the cover held under his chin and it's shaking really fast." being a guy, i already knew what was up, since he was covered, i figured i might as well go look to make sure she's not just jumping to conclusions, i go peek in, and yup he's doing it just like she described, now i'm trying not to burst out laughing... i run back to the livng room, and by this time my mom is more then just curious, she demands to know what's going on.. so we catch her up
mom: maybe he's just scratching
me: ~shakes head smiling~ nooooooooo....
wife: that furiously?
now my mom turns tomatoe red and starts laughing too, we don't go back there, just let him finish up, and all 3 of us end up staring at him funny... later on (not sure, but it was days later) i was talking to him, and i told him what all happened that day, and that we told mom.. he got pissed off, but once i explained that she was back into the suspecting us of drugs thing, he knew i had to tell her, or we'd all pay for it in the end.
