That didn't take long.

Alec Baldwin returned to 'Saturday Night Live' overthe weekend to reprise his role as Donald Trump, mocking the president-elect's prolific Twitter habits in the show's opening skit.

It took just 45 minutes for Trump, on Twitter, to respond.

"Just tried watching Saturday Night Live - unwatchable! Totally biased, not funny and the Baldwin impersonation just can't get any worse. Sad," Trump wrote during the show.
The SNL skit starts by pointing out something that actually happened last week - Trump retweeting a 16-year-old boy named Seth in an attempt to bolster his claim that CNN supported Hillary Clinton throughout the campaign.
"God, Seth seems so cool," Baldwin’s Trump said after retweeting the teenager (played by cast member Pete Davidson). "His twitter bio says he wants to make America great again."
Kate McKinnon, once again playing GOP campaign manager Kellyanne Conway, explained the strategy behind Trump’s Twitter habits.

"He does it to distract the media from his business conflicts and the scary people in his cabinet," McKinnon's Conway said, only to be corrected by Baldwin's Trump.

"Actually, that's not why I do it. I do it because my brain is bad," Baldwin's Trump explains.

The ‘SNL’ skit highlights Trump’s apparently lack of interest in intelligence briefings, even as two aides (played by cast members Kenan Thompson and Alex Moffat) plead, "Mr. Trump, please stop retweeting all these random, real people. You're not getting any work done."
"That's not true. I was elected 25 days ago and already unemployment is at a 9-year low, millions and millions of people have health care, and Osama Bin Laden is dead,” Baldwin’s Trump fired back.
As a Reuters story explained earlier this week, only one member of Trump’s transition team, Geoffrey Kahn, is dealing with the CIA and 16 other offices that represent the country’s intelligence community.
"It seems like an odd time to put issues like cyber security and international terrorism on the back burner," said one senior career intelligence officer, who said briefing books are “waiting for someone to read them.”
The 'SNL' skit goes on to mock two more real Trump retweets, one from “Siberian Husky Lover” @JoeBowman12 and another from @sdcritic, who said “liberalism is a mental illness” in his biography.
Of course, this isn’t the first time Trump has taken to Twitter to criticize how SNL has portrayed him. While still on the campaign trail, Trump called the show “boring and unfunny” and claimed it was part of a media conspiracy that was “rigging” the election for Clinton. 

Then in November, Trump once again blasted the show as "totally once-sided" and "biased," and complained about the lack of "equal time" on the show.

Last night, Baldwin jumped on Twitter to respond to Trump's criticism of the show.
