Upsidaisium
An anti-gravity metal featured on the cartoon series ROCKY AND HIS FRIENDS/ABC/1959-61 & NBC/1964-73. Upsidasium was discovered by Dewlop D. Moose, the uncle of Bullwinkle J. Moose. Rocket J. "Hokey Smokes" Squirrel and Bullwinkle protected the Upsidaisium mine from falling into the hands of Pottsylvanian spies Boris Badenov and Natasha Fatale who sought to use it for their nefarious scheme of world domination. Because the government needs Upsidaisium, Bullwinkle and Rocky fly the mountain to Washington. Also thwarting them at every turn are Mojave Max and Death Valley Dotty (Boris and Natasha in disguise). TRIVIA NOTE: In the 1990s, there was an Australian rock band called "Upsidaisium."
The Urban Dictionary Tee

Not only was the product exactly what I expected, I was well informed on the shipping process in a seamless and timely manner!
The T-shirt was a birthday gift for my girlfriend and she absolutely loved it.

Happy that this tee is comfy and fits well. I wish the sentence was on the back too.
