My, Donovan....you sure have put on some weight. And my.....Donovan, how you have also shrunken. You gotta stop working out in the desert, man. It's killing you.
In all seriousness, though, I've seen that clip 3 times and am yet to make out any resemblence at all to Donovan McNabb. I'm now beginning to wonder if Matt Vasgersian was high. And I love how he was told in his ear that they were live! Although, somehow, I think he knew (or at least as much as you can know after you just took some LSD...)
