Stephen Colbert and Jimmy Fallon both mocked President Donald Trump on Friday night for his inability to articulate.
"I'm not sure if he means 'top dog' or 'leader of the pack,' but either way, he is not the sharpest knife on the Christmas tree," Colbert said, referencing the president's hopes that the U.S. will be leader in the nuclear arms race.

TRUMP STRUGGLES WITH WORDS, AS TOLD BY COLBERT
Reviwing this week's Trump headlines, Colbert illustrated how the president seems to sometimes struggle with words.
"'I am the first one that would like to see everybody nobody have nukes,'" Colbert quoted Trump as saying. "'Everybody nobody have nukes,'" Colbert repeated. "Actually I think that's now nukes work. First everybody has them, then nobody has them, and in between there's a big 'boom.'"
He said: "It's like the Cold War all over again, except everybody's on Russia's side."

JIMMY FALLON'S 'ROSETTA STONE' FOR TRUMP-ESE
Fallon's opening monologue on Friday night included jokes about Trump-ese and Rosetta Stone's "new" program.
"Today President Trump gave a big speech at CPAC," Fallon said, "but I guess foreign interpreters are having trouble translating his speeches because they say it sounds like he's speaking his own language."
Fallon joked: "Trump is so hard to understand, he's thisclose to deporting himself."
"Rosetta Stone just released a new program to help people learn Trump-ese," he said before introducing a spoof of the language-learning software.
