Just go to a sex shop, find the biggest, real looking penis you can find, then flop it out of your fly to show him who the man is.. That should shut him up, or teach him not to pull his out all the time.. And if he knows it's fake, you can always pull it out of your pants and slap the hell out of him with it.. Good luck on the banner, and I agree that you should do it as his work, that is if it wouldn't get him fired..
