For many, Saturday nights in the '90s meant surrendering to the euphoric pulse of happy hardcore. For others, the wildest scenes were unfolding on their TV screens.   This week, Tom and Tomek bow at the altar of Virgo, Black, and Wolf - three icons who somehow managed to transform the blandest of formats into must-watch televisual gold. However, only one of them will end up cheating a project manager from Wakefield out of an uninsurable Land Rover.   Who needs class A substances when a smorgasbord of trick shots, saucy puns, big money balls (and a scotch egg) is being served up in your living room? Awooga!
