Donald Trump apparently has nothing better to do than start Twitter wars with random (perceived) foes, and this time it's "Modern Family" writer Danny Zuker.

It all began with Trump ranting about China: "I've been warning about China since as early as the 80's. No one wanted to listen. Now our country is in real trouble. #TimetoGetTough."

To which Zuker replied, "@realDonaldTrump You've always been tough on China, sir. Particularly the children who make your s---ty clothes."

Trump later tweeted, "Just tried watching Modern Family - written by a moron, really boring. Writer has the mind of a very dumb and backward child. Sorry Danny!"

Zuker zinged back, "@realDonaldTrump Since you're unable to manufacture decent comebacks maybe you could outsource the job to China. #LOL #Trumpelstiltskin."

Danny Z. later scored a knockout blow with, "@realDonaldTrump Doesn't like the show I work on but then we've never tested well with the racist, hypocritical, multiple bankruptcy demo."

We have a feeling that this is only getting started. Thanks to both for one of the funniest Twitter wars we've seen in awhile!
