'“Holy torture chamber, Batman!” Harry exclaimed entering.'
I laughed so hard when I read that, I actually snorted. Owie- and it hurt too... right along with my sides.
Honestly, when the inches started being added to Severus' cock, I thought for sure it was going to be part of the joke too!
LMAO, what on earth have the twins invented that those pants are involved? Ron clearly doesn't know what it does and I'm guessing the twins specifically told him to try it on Harry. Moreover, Harry didn't double of from stomach cramps- it was having those pants suddenly appear on and *in* his body! LMAO!!! Probably a spontaneous orgasm or two hehe. If he ever tries it on Hermione, she'll probably dump him for her pants :-P
