last season, during a performance with brandy, it seemed that near the end of the dance (as he is coming down the stairs), he had popped wood. you can vageuly see an outline of something bulging upwards, and then he proceeds to become conscious of it and even covers it with his hands for a while (i think he also adjusts the growing boner so it is more concealed)
he and brandy also seem to be laughing about it at the very end of the dance as he sits down covering himself.
the clip is available on youtube, but it is the first time they performed this dance, not the second (they did it twice). the song was the theme from Friends (I'll be There for You).
he is absolutely fucking sexy.
