5. Russell Brand
Another one for the bearded contingent out there, and although this one is part-costume taken from when Brand was filming fans-only comedy Arthur, it's still worth pointing out just how ridiculous his strap-on beard looks, as he took off around town in between scenes. Although he was also partial to getting now ex-wife Katy Perry to dress up as, and I quote "a couple of old bag ladies", so they could both swan around town without being bothered, this new amish-style disguise ends up fitting in more with the kind of garb you'd see him sporting on Big Fat Quiz of the Year alongside a vampiric Noel Fielding (back when those shows were worth watching).
