Hey it's called an UGLY Christmas sweater for a reason! Whataburger has introduced their 2018 Whataburger Gift Guide for the Ultimate Whataburger Fan and one of the items is an ugly Christmas sweater, which you can see below. Turns out the sweater was so popular the fast-food chain is already SOLD OUT of them. A note on the website says "We are estimating that Santa will be passing through with another delivery by December 5th." To look this ugly the sweater will set you back $42.99. Will you buy one?
