it's not a detonator (as if they'd know what one looked like)

Really. If I'm good enough to cram a bomb into a pager or a cell phone, you'd think I'd be smart enough to also build in an LCD that looks like it's really functioning. It's not like they call it to see if it really works.

And, in fact, one time, my pager battery died and I couldn't turn it on. They told me to just go on.
