States are like snowflakes: Though some may appear to resemble each other from afar, each has its own unique shape, a basic geographical fact that one company had to learn the hard way.

Twitter user Samantha Ficco tweeted at Wal-Mart last week after discovering that the store was selling a University of Maryland T-shirt featuring an outline of the state of Massachusetts. The shirt included a large white “M” and the word “Terps” (short for Terrapins, the UMD mascot) on a red outline of the New England state.

But Ficco, who was not fooled by the prominent UMD logo and colors, informed the company of the mistake.

At first, a Wal-Mart spokeswoman named Marie defended the shape’s accuracy:

@Samficco The state of Maryland is shaped to dip down on the right hand side which includes the word "Terps" for the team. -Marie

@Samficco On the map, MA and MD are shaped somewhat similarly with the exception of that dip. Thanks for reaching out, Samantha! -Marie

But Twitter users were not buying the excuses:

@Walmart @Samficco Come on! That's a horrible attempt at covering up a mistake. Look at it! Just admit the mistake. It looks better.

@Walmart @Samficco As a Maryland grad who lives in Boston, I would really like to purchase this abomination. Available via website?

A few days later, a different spokesperson, Sonny, retracted the previous comments and offered an embarrassed apology:

@Samficco We’re so embarrassed we may never stick our head out of our shell again! Thanks for guiding this lost Terrapin back to MD! -Sonny

Another Twitter user named Victoria Owens apparently tweeted a photo of the same shirt last summer, though she refrained from tagging Wal-Mart:
