That guy in the blue doggy suit is a young Simon Cowell -- and this is the video his buddy Nigel Lythgoe didn't think we'd ever find. Check and mate. 
Nigel challenged TMZ to uncover the "horrible" video of the "Idol" judge singing -- and did we ever. Here's Cowell waaaay back in '82 on the popular U.K. television show "Top of the Pops" performing as his barking alter-ego "Wonderdog."
Britain's got talent, indeed.

11. I admit that is funny, good find TMZ.
Maybe "Wonderdog." will get the tshirt thief who stole Simon Cowell's tshirt and tried to pick a fight with Mel Gibson.
I still say the idiot paparazzi stole Simon's shirt.

15. I don't get it -- there's no singing in it. Damn -- I wanted to hear him sing. I mean, hearing his over-enthusiasm from within a dog suit is funny enough, but you promised he'd be singing and he isn't!
