My friend Tania put up this photo on her Instagram yesterday, which reminds me of a post I’ve wanted to write about chemistry T-shirts:

Good shirt or greatest shirt? Proud to be wearing #ChemBark Asset #0000003. @chembarkblog #roundbottomflask #chemlife A photo posted by Tania (@prunesmith) on Sep 3, 2015 at 11:12am PDT

That is the most suggestive chemistry T-shirt that I’ve ever had the pleasure of owning. It was gifted to me in grad school by an awesome postdoc. Since it is much too risque for an assistant professor to wear, I felt the time was right to pass it on to the next generation of chemists. I know it is in good hands, as Tania has a collection going:

A quick survey of Google reveals some other dirty alternatives, but I think the round-bottom one is special because it’s from a legit glassware vendor (and one we still use to get our NMR tubes and caps).

Not how you spell that word.

It’s not polite to judge.

This could lead to confusion about the Burgi-Dunitz angle
