The $10 t-shirt deal of the day over at RIPT Apparel is a mash-up of Firefly and Jurassic Park called “Jurassic Betrayal” by artist perdita00.

The shirt went on sale at RIPT today, Saturday, June 11, 2011, 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 design takes the logo for the movie Jurassic Park and changes the title to “Inevitable Betrayal,” which is based on a scene from the Season 1 Episode 1 Serenity of the television series Firefly.
