Most of the tees I highlight in these posts are merely novel combinations of two pre-existing creative entities, ranging from TV to movies to video games to books. Internet-era creativity has generated an exponentially increasing number of deep cultural callbacks. As a shirt that blends together many of those references, you could say that this is the nerd shirt to end all nerd shirts.
It's a mash-up in mash-up about mash-ups. Who wouldn't want to put that on their chest?
"We're All Mash'd Here" is currently available on The Yetee for $11 until 1:00 Eastern on April 2. The shirt may be available at a later date from a different retailer for a different price.
