Inquiring minds want to know

So here's a question that has troubled me for some time...

...in the Dell computer "Lollipop" commercial, the first guy starts singing the lollipop song and is quickly joined by a second guy...it's that second guy who puzzles me. He pops up from below while buttoning his overalls.

So...what was he doing on the floor?

And what was he doing on the floor with his coveralls unbuttoned?
