One of the clues in tonight's Race was a tie-in to the Tin Tin cartoon. The racers were dressed in costumes that looked like Charlie Chaplin, but that wasn't what they were depicting. Here is what they were:

"Thomson and Thompson (original French: Dupont et Dupond) are fictional characters in The Adventures of Tintin, the series of classic Belgian comic books written and illustrated by Hergé.

Thomson and Thompson are detectives of Scotland Yard, and are as incompetent as they are necessary comic relief. While the two are apparently not related as they have different surnames, they are twice referred to as twins or brothers in the original language version of the series.[1] In any case, the two detectives look like twins and can only be told apart by the shape of their moustaches (Thomson's moustache flares out a tiny bit on each side at the bottom).

They are afflicted with spoonerism, are extremely clumsy, are thoroughly incompetent, and usually bent on arresting the wrong character. In spite of this, they somehow get entrusted with delicate missions, such as ensuring security for the Syldavian space project or investigating arms dealing.

The detective with the flared moustache is Thomson (without a "p"), who often describes himself as "Thomson, without a 'p,' as in Venezuela!" and who often remarks, "To be precise...". The detective with the flat moustache has described himself as "Thompson with a 'P,' as in..." and then used words with either a silent "P," or in which the "P" is combined with another letter, losing the "P" sound, such as Philadelphia, psychology and so on."

I love this play on words, will probably watch that movie just to see these guys.
