The $10 t-shirt deal of the day over at TeeFury today is a Firefly-themed shirt called “I Aim to Misbehave” by artist nakedderby.

The sale began at Teefury today, Monday, August 22, 2011, at midnight EST, 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 in dark chocolate for $10 each.

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

I recently was introduced to the genius that is the “Firefly” television series, and the feature length “Serenity” film, and I fell in love with every thing about it. The end result is this design.

Leave it to me to discover a brilliant TV show about 10 years too late. Thank goodness for dvd box sets…
