Sliding Doors

I've noticed I have this thing for drawing doors that slide open instead of being pushed open.

Have I ever drawn anything good coming through a slowly opening lab door?  Has anybody?

Also, while I was drawing G.E.R.L. this month, I tried to include more sound effects, although it got to be a bit of a chore trying to decide what certain things would sound like.  I hate to use cliched sound effects, but sometimes there's not really any other way to say "boom."
