I lay awake and strap myself in the bed
Put a bulletproof vest on and shoot myself in the head (Bang!)
I'm steamin mad (Arrhh!) And by the way, when you see my dad (Yeah?)

Mainly the bulletproof vest part. That's genius humor. It may not seem like it is, but when you're randomly listening to the song, and you hear that. It makes you go, "What the FUCK?" *REWIND* "HAhahahaha that's great, you hear what he just said?"
When you got people doing that, you're doing something right.

Punchlines are great, but they can get old, and Eminem isn't the best person for punchlines, let's face it.
