My Son, The Old Fart

My son, lying on the sofa (home sick all day), watching TV...
Me, sitting nearby (working on computer)...
I overhear something like the following:

Pat: Well, Dan, you've won yourself a bundle and a nice little trip! You've got $10,800 so far!

Dan: Whoo hoo!

My Son, the Old Fart: Whoo hoo, Dan, maybe now you can buy yourself a decent haircut.
