As a kid, my dad would play a bunch of Nirvana cds. I always thought the line in Smells Like Teen Spirit that said "Here we are now, entertain us" was "Here we are now, in containers".
I always pictured Kurt Cobain asleep in some sort of test tube, sleeping, like in a container for scientific study or something.
