It's a Cameo. You pay like $250 and he records a 30 second video and will read from your script (minus racist, illegal, inappropriate stuff etc).
I'm quite surprised that FOX let's him do Cameos as you can repost them & make it look like he's biased etc. In reality he's just reading from your script. Hes probably done the same thing for FSU, Tennessee, Michigan St, etc
Cameo is usually reserved for washed up former stars who need the $$ like Eric Estrada or The Office side characters. Odd that FOX allows him to do these when he's still employed etc.
