For this we need a node?
Well, maybe. But I was actually inspired to node this because of a bit of lyric:
8 o'clock, Monday night and I'm waitin'
To finally talk to a girl a little cooler than me.
Her name is Nona, she's a rocker with a nose ring,
She wears a two-way, but I'm not quite sure what that means.
-- Girl All The Bad Guys Want, Bowling for Soup.
But, I'm not quite sure what that means. Google couldn't tell me. Onelook couldn't tell me. Even E2 couldn't tell me. If you can tell me, /msg me, and I'll add it.
-- Chinakow reports that the song refers to a two-way pager. I have no reason to doubt him.
