Dan Hogg is thrilled when his uncle offers him some work at a food fair, because he wants money to hire a professional trainer to help him with his scrawny physique. His excitement vanishes when he learns that the job is dressing up in a hotdog costume and handing out samples.

It's not until he's huddling in a bathroom in his tight white underwear that Dan begins to suspect Brooke's attention might be too good to be true.
