Booster has $500k to burn, says I'd like to spend it to recruite kid X (or favorite coach's prospect), kid accepts, once on campus booster says if X comes to sign autographs at my 3 yr old's birthday party I'll give X the $500k. Or maybe its $100k/yr so you gotta show up for the 3 yr to 8 yr party. Even the three year old gets it.
