Colin and Fergus are clean-cut twentysomethings with ready smiles, fetching dimples and twinkly eyes. You could be introduced to them a dozen times and still not remember which is which. They joke about sex, but you can't imagine them actually having it. Even they compare themselves to Ant and Dec. The difference is that Colin and Fergus have some talent.
This sketch show brings out both the glib and the gifted in them. There's a scattering of slightly skewed party games, on the lines of Get Off Of My Land (a farmers' version of Grandmother's Footsteps); some northern bigots in flat caps ("We all know that homosexuality started in the south"); and a comic serenade to a member of the audience. That's all very enjoyable, but hardly innovative. More promising are some dreamlike skits where the rules of nature are suspended and the pair switch between roles with only the slightest attempt at characterisation.
I particularly liked the opener, in which Fergus-or-Colin arrives at Colin-or-Fergus's home as a policeman needing "a chat", turns into a librarian who wants to spend the night, and ends up as a 14-year-old of indeterminate sex, calling his host a dirty bastard and denouncing him to the police. There's a real lightness of touch in these scenes, though you wonder if the toothsome twosome have any choice in the matter.
