Yes, I recall watching him at the Olympic Games. Do you know how many medals he has won?
He is actually the most decorated and successful Olympian of all time with a total of 28 medals 
That's impressive. I remember watching him at the Beijing Games. How many did he win there?
When he was at the Beijing games he won a total of 8 gold medals!  Isn't that amazing!
Wow, he is a beast! What are some of the records he holds?
At the Beijing games he broke fellow swimmer Mark Spitz 1972 record of seven first place finishes at any single Olympic Games
