The $10 t-shirt deal of the day over at Teefury today is a Super Mario Bros.-themed shirt called “Say No To Drugs” by harebrained.

The sale at Teefury began at today, Monday, July 23, 2012 at midnight EST and will continue for 24 hours from then, and once it’s over, it won’t be sold at the site for $10 anymore, though it might continue into the next day for $13 (look for the After Hours bar at the top).

The t-shirt is available in Men’s and Women’s sizes in black for $10 each.

From the artist:

Its based on this story my plumber told me. I guess he ate some mushrooms and tripped really hard. Actually, some company made his story into a video game.

What do you think of this design?
