It could start off with pre-recorded footage of the opposing team's mascot going in for an interview with big shot Willie. They could be all nervous and stuff and probably trip or something when they came in to meet him. Willie would probably find it adorable and a bit endearing and decide to help them out. After the awkward interview Willie would ask them to dinner at his place. He'd pick them up in his helicopter.
That's when the real helicopter would enter BSFS with Willie and the other mascot and land at midfield. Then Willie would take his shirt and tie off and lead them to the purple room of pain. He'd probably tie the other mascot up with his tie and bar its legs with a block of wood that said "family" on it. During this sordid ordeal, we'd play old footage on the jumbotron of other teams just dominating the cats portrayed as Willie's suppressed memories. Then Willie would finally untie the other mascot and they could hug and then they'd get married. The end.
Oh yeah, song is "no more tears."
