"I know, it's crazy...but I guess that explains..." He was going to say it explained why he'd been so twitchy with cards in the first place, possibly why he'd started to reach for cards as a weapon--because that's where he knew this one was to be stored in his monster form--but then Bakura's speaking in Egyptian registered with him. He said a few things in his own monstrous language, mostly about cards and belt buckles and things the language actually had words for. He then broke off in a giggling fit that threatened to make him fall over. Even though he'd said nothing funny, it looked like he was laughing at some private joke.
