On this year’s Valentine’s Day episode of the CBS sitcom The Big Bang Theory, the character Leonard (played by Johnny Galecki) is seen wearing a 2012 Great Lakes Bat Festival T-Shirt.

That shirt is available on sale right now at the Bat Con online store for only $10.

According to the Organization for Bat Conversation, a non-profit dedicated to the welfare of bats and preserving their habitats through education, collaboration, and research, the shirt features the following bats species: (clockwise, starting at the top) an Indian Flying Fox, False Vampire Bat, Greater Bulldog Bat, and the Mexican free-tailed Bat.

Grab this shirt now while it’s on sale and contribute to a great charity to help the bats! (I already own the shirt and I paid $19 for it!) Visit batconservation.org to learn more about the organization and check out their donations page if you’re interested in donating to this charity and/or sponsoring a bat.
