I swear, I forgot about the pipe bomb!

In a bizarre story, a college student was detained in Oklahoma City airport after a pipe bomb was found in his luggage. He says he "forgot" about the pipe bomb.

WTF?? I don't care who you are, you don't "forget" about a pipe bomb! This is not a pair of friggin nailclippers. What does "forgot" mean anyway? He forgot to take it out of his suitcase? What the hell was a pipebomb doing in his suitcase to begin with? This whole thing is just absolutely bizarre.
