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

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.

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.
