Team USA is at the opening ceremony and there's a lot of picture-taking going on

Team USA is at the opening ceremony and they are all very excited to take photos together.

After four years of hard work, the United States Olympians are making their way into the opening ceremony for the 2016 Games and it seems the first thing on all the athletes’ lists of things to do was taking picture with other athletes.

A few of the competitors even found some of their schoolmates.

Earlier in the day the gymnasts stopped by the men’s basketball team practice, leading to some very hilarious size differentials.

The U.S. delegation of 554 athletes will be lead by flag bearer five time-Olympian Michael Phelps, who is seeking to add to his lifetime total of 22 medals, including 18 golds.

The opening ceremony begins at 7 p.m. ET but NBC’s broadcast of the event will not begin until 8 p.m. ET.
