We heard Green Day on the radio today. We discovered the band years ago, before they got really big, on a televised concert. One of those random channels you discover when channel surfing because nothing else is on. We stopped and watched because the lead singer looked strikingly like our friend Bob from college.
Ok, he looked strikingly like Bob if Bob had been into eye makeup and tattoos (which he wasn't, that we ever saw). Really, the resemblence is mostly in haircolor and face shape. However, it was enough. The singer was immediately dubbed "Bob's Evil Twin".
We still refer to Green Day's lead singer as Bob's Evil Twin. Eventually, we even bought one of their albums, but any mention or image of the singer leads to that reference.
I'm not sure it's the way Bob would like us to think about him, but it does make us think of him!
