Video: Racing presidents moonwalk in tinfoil helmets for visiting astronaut Kjell Lindgren

In his recent 5 month stint aboard the International Space Station, astronaut Kjell Lindgren likely never saw anything as alien-looking as the sight that greeted him at the presidents race finish line Tuesday night at Nationals Park.

Lindgren is in D.C. this week to speak about his mission and promote space travel to the next generation of astronauts, so there he was in the fourth inning, holding the Nationals’ presidents race finish line tape along the first base line.

What emerged from the centerfield gate caused more than a few fans to wonder what was going on: six giant figures running around the warning track with their heads wrapped in aluminum foil.

“It looks like they’ve all made their own space helmets,” explained Nationals Park PA announcer Jerome Hruska as the presidents dashed toward Lindgren. “They’re headed into the right field corner, and we’re not entirely sure who’s who!”

Then, just before hitting the tape, they all stopped, turned around, and began moon walking to the finish line. Video below.
