During a speech Saturday, Donald Trump let the crowd know that he has a lot of problems with opponent Ohio Gov. John Kasich (R), including the spelling of his last name.

While speaking to a crowd in Connecticut, Trump started on a tear about how many more millions of votes he has than Kasich and Sen. Ted Cruz (R-TX). During that portion of his speech, he stopped to wax poetic about the correct way to pronounce “Kasich.”

“I don’t know how to pronounce his name — Kasich. It’s -i-c-h,” Trump said in a video reported by ABC. “Every time I see it I say Kas-itch. But it’s pronounced Kas-ick.”

Trump went on to call the ordeal of pronouncing his name “ridiculous” and asked the crowd if he could ask Kasich to change the spelling.

“So I’m doing a very good job saying it…Can we ask him to change the spelling of his name? Are we allowed to do that? It’s so ridiculous,” Trump said.
