The $9 t-shirt deal of the day over at Teefury today is the Fantastic Four – Sesame Street mash-up “The Sesame Six,” by artist AJ Paglia.

The sale at Teefury began at midnight EST (Thursday, February 3, 2011) and will continue for 24 hours from then, and once it’s over, it’s gone from the site for good.

The design shows the Sesame Street characters as members of The Fantastic Four superhero team, with a background made to look like a FF comic book cover. The story title here is called “Attack Of The Grouch” and shows a Burt/Ernie hybrid stating “Our weapons are useless!” (against the attacking Grouch, of course).
