Well, here's an odd trio.

Michael Jordan and Wayne Gretzky -- perhaps the greatest stars of all-time in their respective sports -- sat down to get their picture taken last month. And, of yeah, Kid Rock was there, too.

Gretzky's wife, Janet, posted the picture to her Instagram account last month, prompting many to ponder what spurred on this unlikeliest threesome since running, swimming and biking hooked up to form the triathlon.

Maybe this will start a trend. Who wouldn't want to see a photo of LeBron James, Tom Brady and any of the New Kids on the Block? Or Mike Trout, Sidney Crosby and the lead singer from Chumbawumba? Or Tiger Woods, Tony Romo and everyone from Night Ranger?
