Donald Trump and John Oliver fought it out on Twitter over the weekend

In true Donald Trump fashion, he wasn't going to let John Oliver's insults go unanswered.

Last week, Oliver said he would never have the the Republican presidential candidate on his show.

"I really don't have anything to say to him," the 38-year-old comedian said Friday on "CBS This Morning." "He's said everything he wants to say. He has no internal monologue, that man. So it's not like you're going to find the secret nugget he's been holding back. He's an open book. That book doesn't have very many interesting words in it."

On Saturday, Trump then hurled insults about the show back at Oliver and claimed that he had been invited to the HBO talk show.

.@thehill John Oliver had his people call to ask me to be on his very boring and low rated show. I said "NO THANKS" Waste of time & energy!

But John Oliver and his team weren't about to let Trump's comments stand. On Sunday, the show denied ever asking the real estate mogul on, but it was able to find some common ground.

 Another area in which the two parties agree: Neither wants Trump on the show.
