Sen. Ted Cruz is enjoying infuriating the establishment so much that he's got his own "wacko bird" hat, a reference to a swipe John McCain took at him. He picked up the black hat from supporters in Texas, GQ reports, but that's far from the only fan-made wacko bird merchandise available. Cruz may not have a friend in Sen. John McCain, but he definitely has one in the Internet.

Back in March, McCain said of Cruz, as well with Sen. Rand Paul and Rep. Justin Amash, "It's always the wacko birds on right and left that get the media megaphone." Cruz fans seem have taken on that moniker as a badge of honor, one displayed in remarkably imaginative ways by amateur T-shirt designers. There is a ton of wacko bird merch on Zazzle, CafePress, and eBay — here are some stylish options, should you want to wear your wacko bird pride. 

Here, we have some wacko birds circling a rhino/RINO:

Imagining a Bald Eagle as a wacko bird is a common theme. 

So is invoking the Constitution.

Some bumper stickers employ inventive spelling, but the sentiment is the same.

And of course, the best pro-Cruz merch is merch that is also anti-McCain. Great play on the word "right" here. 

And the back of the above shirt:

Angry Wacko Birds attack Bad Piggy McCain.

And the pièce de résistance

Poor Old McBuzzard. As we learned in GQ today, Cruz has no sympathy for McCain. He told the men's mag, "I don't know a conservative who didn't feel embarrassed voting in 2006 or 2008."
