As you know, Ted Cruz is the butt of a long-running joke that suggests he's the Zodiac Killer. This is obviously not a compliment, nor is it something the Cruz family seems to find very funny.

And yet, it appears on Wednesday Cruz decided (about a year and a half too late, we might add) to get in on the joke:

Perhaps you're wondering: Why did Ted Cruz, a sitting U.S. senator, choose today to compare himself to a serial killer?

Apparently, it all started during Attorney General Jeff Sessions' Senate hearing.

Per CNN, Senator Ben Sasse opened his line of questioning with an apology, noting that he'd "dumped a Dr. Pepper on Senator Cruz, so that was what was distracting us on this side of the dais."

This, predictably, went over well with Twitter.

Later Sasse joined in on Twitter, responding to a tweet that (jokingly) suggests that Cruz is the son of Lee Harvey Oswald and therefore deserved a Dr. Pepper spray. (Yes, that's a meme, too).

And in response, Cruz tweeted a photo of one of the Zodiac Killer's infamous coded letters, reigniting the joke. If Cruz ever hoped to escape the meme, he's now personally seeing to it that the joke lives on for the foreseeable future.

If you've been sitting on a good Cruz/Zodiac Killer tweet, now's the time to dust it off.

Of course, as with the recent NSFW tweet that Cruz's account liked, this whole thing might be blamed on an intern or a hack or something. Whatever it is, we're just glad to see this weird, random joke resurface.
