It's apparently been a well known joke for years but is this the University of North Texas' way of letting us know they're finally in on it? Or did they just not spot this gaffe?

We won't spell out what exactly is wrong with the official University mug in the picture below, we'll let you do that for yourselves.

Not sure the University of North Texas thought that through

If you don't believe that it's legit then take a look at the Barnes & Noble page that it's listed on.

We hope this is the work of an office prankster in which case we tip our hat to them but it's more likely that the University of North Texas really didn't think this mug through properly

We're the winners regardless.
