"I was, as a young man, I was born in a coal town of Scranton, Pennsylvania, northeastern Pennsylvania, in an Irish Catholic neighborhood. Then when coal died, we moved down to Delaware, to a town called Claymont, Delaware, which was a working-class town, but everybody in town was either Polish or Italian. I grew up feeling self-conscious my name didn’t end in an S-K-I or an O," Biden said.

He continued, "But all kidding aside, the connection between — I was telling the president, the pride, the overwhelming, demonstrable pride that Polish Americans feel about Poland and the role you are playing now, we were talking about it, it is extreme. It is. You would be — if you haven’t seen it, you should come and see it."

BIDEN’S UKRAINE AID A ‘BLANK CHECK’ TO CHINA TO ‘BLEED US DRY,’ EXPERT WARNS 

Several social media users pointed out that Biden has frequently claimed to have grown up in various communities depending on his location, most notably the Puerto Rican community.

Newsbusters director Jorge Bonilla joked, "Biden betrays the Puerto Rican neighborhood of his youth, pines for Polish-sounding last name."

"I thought he was Puerto Rican, and raised the a black church?" actor Dean Cain asked.

"For those who haven't been paying attention, Biden is half half Puerto Rican, half black, half Jewish, half Republican, half Polish, half Italian, and half coal miner," Grabien founder Tom Elliot tweeted.

Conservative author Doug Powers remarked, "Biden’s story about the people he grew up around changes depending on who he’s talking to. Any of the ‘fact checkers’ want to get on this one?"

"His entire meeting with the Polish leader was a rambling mess," National Review contributor Pradheep Shanker wrote.

"Biden jokes to Polish president that he wants to add 'ski' to his name. Totally appropriate, considering we are on the brink of a nuclear World War III. Dementia Man is a global embarrassment," commentator John Cardillo tweeted.

While visiting Puerto Rico following the destruction from Hurricane Fiona in October, Biden remarked, "We have a very… large Puerto Rican population in Delaware. I was sort of raised in the Puerto Rican community at home, politically."

In addition, Biden has frequently claimed to have attended a Black church as a teenager despite longtime congregants insisting that they never saw him.

"Let's lay one thing to rest. I may be a practicing Catholic, but [I] used to go to 7:30 Mass every morning in high school and then in college before I went to the Black church," Biden said. "Not a joke."
