I was just watching this and the episode that was on was the one where lois went out of town, hal tore apart their bedroom, and malcolm's friend, dabne or whatever, had his birthday party. For his birthday he got a paintball gun from his grandfather and they call it some weird name and say it's the best gun you can buy, and it's not clear what kind of gun it is (i thought it was a spyder or a blowback marker of the like). Well when they actually go paintballing you can clearly see he has a classic mag with an annoed hard line and powerfeed, as does everyone else. I thought this was cool, though i'm sure some may find it pointless.
