I love Michael Fred Phelps,he's a great swimmer in the Olympics
I've heard of him, but I really don't know much about him.
You don't follow the Olympics?  Phelps also holds the all-time records for Olympic gold medals (23), Olympic gold medals in individual events 
Oh wow, I had no idea! He must be an incredible swimmer!
Also,When he won eight gold medals at the 2008 Beijing Games, Phelps broke fellow American swimmer Mark Spitz's 1972 record
Which record did he break of his then?
He's a consistent record breaker,  At the 2012 Summer Olympics in London, Phelps won four gold and two silver medals, and at the 2016 Summer Olympics in Rio de Janeiro.
Damn he must be so good then! What other gold did he win then?
