It was long, but I don't doubt that the whole thing aired. Hell, the most hilarious Conan ep. ever featured 10+ mins of Triumph pooping on Star Wars nerds. I feel proud to have seen that on its original airing. Interestingly, it seems Triumph has moved on to bigger, [yet] disappointingly less as funny gigs. Karma?
DISCLAIMER: I don't yet actually drive a BMW. Currently, I proudly drive a '93 Volvo 940, the inspiration for my love of RWD cars.
