The day has come. No longer must you order a vanilla shake at Whataburger and then run it under the Dr Pepper soda fountain. 

(That's a float.)

Mark this one down as a Texas holiday, y'all: Whataburger is now offering a Dr Pepper shake. Rumors of the new shake begin circulating on social media this week. The timing had some concerned it was an April Fool's joke, but Whataburger tweeted to confirm that the shake is very real and the only thing that's funny about it is how many fans can slurp up in its limited-time offering.

Remember -- breakfast is fair game, guys.
