#3: Science vs. Religion
One of many witty t-shirts, this falls into the somewhat obscure but definitely well-loved sub-category of Chemistry/Christianity puns. I believe this category has a lot of potential and could be expanded to include tees about Adam and atoms, ester and Easter, or radiation and redemption.

We just hope that no one takes offense to this one, whether it’s devoted religious Catholics who wouldn’t set foot in a laboratory or avowedly atheist scientists who wouldn’t be caught dead in Church. This shirt could be inflammatory to one group or another, and we just want to ensure all our readers know that we promote coexistence.
