Jus what are they implying?

Here's a video of a Dell laptop commercial. I thought it a bit strange.



Did you notice anything strange? I assure you it has nothing to do with the similarity between making candy and the manufacturing of electronics. The comments on youtube proves that I'm not the only one who thinks there is something fishy going on.

The lights turn on. Check

Guy comes up from below frame. Check

Other guy comes up from below frame, smiles at first guy, and straps on his overalls. What?

So why was that guy's pants off? I worked in a factory before and I always had put my pants on before leaving the house. Was this guy sleeping on the floor of the factory without his pants on? I doubt that guy was ad libbing. I can only assume that someone actually told him, "When you get up and start singing, buckle up your overalls." Why would someone suggest that? What does it all mean?
