Stephen Colbert sad Donald Trump clearly struggled during a visit to a Pennsylvania supermarket this week.

“In his attempt to connect with the common man, Trump had no idea how to answer the simplest shopping question,” Colbert said as he rolled a clip of Trump in a supermarket being asked what he would buy there.

“I don’t know,” Trump said. “You know, because of what I do, I haven’t been in these stores in a long time.”

Colbert broke out his Trump impression.

“You know, it’s so nice, this is amazing, this is fun for me because it’s so nice to see where all the food lives,” he said. “I usually don’t get to meet it until the man comes in with my sauce-filled nuggy bucket.”

Colbert noted that Trump seemed to get excited when he spotted some popcorn ― but never actually used the word.

“Oh, look, I gotta get some,” Trump said. “Look at that stuff! We gotta get it.”

“OK, he clearly just forgot the word ‘popcorn,’” Colbert said.
