The University of Cambridge Zoological Museum has a rather wonderful box of beetle specimens collected by Charles Darwin when he was at the university. The young Darwin had an inordinate fondness for beetles.
Darwin's son, Sir Frances Darwin, donated his father's beetles to the university. The collection was originally in a cabinet. Unfortunately, in the 1870's, one G. R. Crotch began sorting some or all of the collection into boxes, all but one of which was later lost/misplaced.
Charles Darwin Quote
One day, on tearing off some old bark, I saw two rare beetles, and seized one in each hand. Then I saw a third and new kind, which I could not bear to lose, so I popped the one which I held in my right hand into my mouth. Alas! it ejected some intensely acrid fluid, which burnt my tongue so that I was forced to spit the beetle out, which was lost, as was the third one.

He put a Bombardier Beetle in his mouth. And this is the guy who you base a show on called "The Genius of Charles Darwin"? LMAO
