Your Guess Is As Good As Mine

A friend offered me 20 bucks if I could tell them what Serena Williams was doing out in London with Common recently. Um, well her panty hose are a little busted up but she doesn't look hurt. Common's lips look a little glossy but I doubt if they were lip locking. Hmmm, let's just say they look like they are about to make one hell of a collaboration. Who knew Serena could sing???

Where's my 20?
