The most talked about moments from Tuesday night's Olympic action

(CNN)The big social talker of the night came when Michael Phelps crushed rival Chad le Clos in the 200-meter breastroke final.

Michael Phelps of the United States leads Chad le Clos of South Africa in the men's 200m butterfly final on August 9 in Rio de Janeiro, Brazil.
Le Clos didn't even medal, much to the delight of many Twitter users.
    For a moment, Le Clos' Wikipedia page had an interesting addition.
    And this was a common sentiment...
    Phelps was later seen laughing during the US national anthem, which prompted some criticism and this clarification:
    "My boys from Baltimore were down on the other end, and back in Maryland, we all say "O!" for the Orioles during that part of the national anthem. And all of the sudden I hear them roar "O!" and I knew exactly where it came from, and I just lost it because those guys came down from Baltimore and New York City to be here, and it's just special to see those guys in the stands," he told NBC.
    The US men's basketball team fanboyed hard when the Americans won the 400-meter relay:
    And if you were wondering why Phelps' name wasn't on his swim cap during the relay, it's because he ripped his right before the race. Luckily, teammate Conor Dwyer lent him his.
    Not keeping track of how many medals the US men's swimming team has? Fear not:
    The US women won gold in the team gymnastics competition Tuesday. The team's nickname -- "Final Five" -- trended for hours following their win.
    Katie Ledecky swam fast. How fast, you ask?
    Ryan Lochte also made some history, though you'd be forgiven if you didn't notice.
    But people seemed more interested in his silver hair.
    Or is it green?

    Speaking of green...

    The Olympic diving pool turned a mysterious shade of green, sending puzzled Twitter users into a frenzy. What was going on in that pool?
    Team GB's diving star Tom Daley wondered, "what happened?"
    It was "nice of Shrek to hire out his swamp for the Women's synchronized" diving, quipped one user.
    Officials said Wednesday that algae was to blame, but there was no need to worry as the water quality "was tested and there were no risks for the athletes." Phew, that's alright then.

    Body shaming

    Elsewhere, Alexa Moreno was the latest target for Twitter trolls after they posted a series negative comments about the Mexican gymnast's weight. Moreno competed in the women's uneven bars, beam, vault and floor exercise, finishing in 31st place.
    Mexico's Alexa Moreno competes in the qualifying for the women's Beam event of the Artistic Gymnastics at the Olympic Arena during the Rio 2016 Olympic Games in Rio de Janeiro on August 7, 2016.
    Many came out on Twitter to stand behind Moreno, sharing the hashtag #AlexaMoreno to say she was "admirable and respectable."
    An Ethiopian Olympic swimmer also found himself the butt of unkind jabs, with some dubbing him "Robel the Whale" after he finished half a lap behind his rivals. Robel Kiros Habte completed the 100m race in 1 minute, 4.95 seconds, nearly 8 seconds behind Sirish Gurung from Nepal.
    Robel fans came out in force to support him for finishing the race, with one tweeting, "First cheer at the #Rio2016 pool goes to Ethiopia's Robel Habte. Not quite Eric the Eel but close."
    Shame on you, bodyshamers.

    Olympic delight

    Fu Yuanhui is clearly happy to be at the Rio Olympics.
    The swimmer delighted the Internet by pulling a series of funny face to express how happy she was at securing a bronze medal in the women's 100m backstroke.
    "Must be a joy having her around," said one tweeter.
    Watch out Jim Carrey, Fu might steal your crown.
