Who's got next? Michael Phelps is asking because he may want in.
After Conor McGregor took his talents to the boxing ring against Floyd Mayweather on Saturday, fans are wondering what the UFC star will do next.
Phelps, a 23-time Olympic gold medalist, chimed in on Tuesday with a funny idea: He could come out of retirement and challenge McGregor in the pool.
Phelps is likely referring to a "Saturday Night Live" skit that joked about McGregor's endless pursuits.
On "Weekend Update," McGregor -- played by actor Alex Moffat -- proclaimed, "I'm going to fight that shark [that] beat Michael Phelps in that swim race!"
Let's just hope that if this somehow comes to fruition, it won't cost us a foot and a leg.
