How about putting them in front of a tv together, squirming, watching a show that they don't want to miss anything of. After a while one of them could say something like: "Don't pee on my chair", at which the other responds: "I can do this longer than you". Resulting in a friendly, somewhat playful holding competition, in which none of both wants to give in: "I'm not going first. For God's sake, you go".
