Basically, if you ram your head against a corner like this, one of the three things will happen (from most common to least common):

1. Nothing
2. Beemis will repeatedly smack his head against the ground/wall
3. Warp to the ground.

Haha yeah I have had this happen multiple times here and during Sbubmund fight. Finding a way to have it port you inside or somewhere important would be pretty cool.
