The wall between Mexico and the US is one heated point of discussion and one that may have brought the President ship to Donald J. Trump.
On this t-shirt, you can see the famous Mexican mouse Speedy Gonzales from the Looney Tunes and Speedy says “Hey Gringo! I Found A Hole In Your Wall”.
So it is a funny t-shirt making it clear that there are always ways to get over, under, or through the wall especially if you are a tiny mouse, like Speedy Gonzales.
