Future TBS late night host Conan O'Brien began his "Legally Prohibited" tour this week, and here's your first look: O'Brien doing a ridiculously cockneyed Thom Yorke impression while singing Radiohead's signature hit, "Creep". This was just the sound check, so the show must be amazing. If you have tickets for a future date, however, you may want to avoid videos of the tour so it won't spoil any of the surprises you paid at least 40 dollars for. This one should be okay though because, again, it's just the sound check. But what a sound check!
