Huh? What? Come again?

My son is a trip, I mean when it comes to some things he just doesn’t have a clue sometimes.  For example my hubby surfs the web a lot on his laptop (that reminds me I need to clean up his computer, he never cleans his temporary Internet files or anything) and he is always logging into his profit sharing area to see how he is doing. He was doing a search on futures broker and my son thought it was a site for employment as he said to my hubby are you looking to get a new job in the future?  My hubby looked puzzled for a moment and said huh?  What?  My son has this huge bad habit of “ease” reading when anyone is on the computer.  I wonder maybe next week I will do it to him during his classes online when he is trying to do his school work and see if he likes it!  Can we tell it’s late and I lost all my patience for the day?
