The $10 t-shirt deal of the day over at RIPT Apparel is a Monty Python-themed shirt called “Knights of Ni Crossing” by Studown.

The sale at RIPT began today, Sunday, February 12, 2012, at midnight CST, and will continue for 24 hours from then, and once it’s over, it will not be sold on the site anymore.

The t-shirt is available in men’s and women’s sizes for $10 each in black. Kids sizes are $15 (Boys, Girls, and Toddler in black); Onesies are $18 (in black). You can also get the design on a Hoodie for $38 (in Men/Unisex sizes in black).

Here’s what the artist had to say about this design:

This shirt comes from an idea I had while watching Monty Python and the Holy Grail. What if there were a sign posted in the forest alerting travelers of the Knights of Ni, along with a clue as to what to do upon meeting them. Would they say the right word?

What do you think of this design?
