If you’re wondering why Reebok’s viral ad campaign of famous people working out in the nude featured two athletes (Chuck Liddell, Chad Ochocinco) and an actor (Dax Shepard), the answer is in this video from their appearance on "Jimmy Kimmel Live." First of all, we all know that comedy comes in threes, so there’s that. Second of all, somebody has to be articulate enough to carry the segment with Kimmel, so that’s where Shepard comes in.
Face it, if you left the whole thing up to Liddell alone it’d be four minutes of short, mumbled sentences and at some point Kimmel would get frustrated and just flat-out demand to know what’s up with those weird jeans. That’s why you bring an actor along, people. He diffuses the situation and takes the pressure off you in his constant, cloying search for love and acceptance. When an actor is unavailable, a puppy will work just as well and for the exact same reasons.
