Product placement often seems to be most easily integrated into comedy, and the WWE often finds a way to put product placement in its programming very blatantly but in a way that makes fans laugh instead of gag.
WWE Owner Vince McMahon acted as judge and was biased against Bischoff, his long-time enemy. For instance, when one witness for Bischoff finished talking, McMahon admitted he hadn't heard any of it.
Later, "prosecutor" Mick Foley opened his old-school Batman lunchbox during a recess and pulled out an RC Cola and a Moon Pie, an homage to the stereotype of the south but embraced by the fan favorite in a way that got a chuckle out of the fans.
When product placement ends up being part of the most entertaining parts of a show, you know a company has found a potential landmine in profit while still retaining a show's integrity for its loyal fan base.
