Trump responds immediately to 'Saturday Night Live' skit mocking his tweets

Well, that was fast.

The Donald Trump-themed cold opens keep coming on Saturday Night Live, this week with more jokes lobbed at the president-elect for his prolific Twitter account.

Within an hour of air time, Trump had responded on, you guessed it, Twitter.

"Just tried watching Saturday Night Live - unwatchable! Totally biased, not funny and the Baldwin impersonation just can't get any worse. Sad," Trump wrote before the episode had concluded.

Alec Baldwin wasted no time hitting back at Trump.

"Release your tax returns and I'll stop," he tweeted.

Hosted by Emma Stone, the episode introduced viewers to the show's best guess as to who the president-elect has been retweeting as of late: There's high school student Seth, a random dude with a Twitter bio of a skull and the word "infidel" above it, a guy on a date.

"Seth, you're just a kid in high school, who would retweet you?" asked Aidy Bryant as a high school teacher.

"Seth seems so cool, his twitter bio says he wants to make America great again," says Alec Baldwin as Trump.

The skit went on to skewer Trump's comments to television executives and anchors about using photos of him with a double chin, his dinner with Mitt Romney and his chief strategist Steve Bannon, who they painted as the Grim Reaper.
