The caption may as well be "An erection!"* If there is anything I remember Gene Wilder for, it's his performance in Blazing Saddles, where he laughs in the face of his hardships. I get that anxiety is a potent source of comedy--mostly because that's where my bite comes from--but I don't necessarily want to remember a great only in terms of his ennui.
These are two sides of the same coin, and we need to celebrate both of them.
(To be fair, most of the obituaries I've read have been pretty fair, I just really, really hate this picture of Gene).
*From Waiting for Godot: Vladimir and Estragon are waiting for the eponymous Godot, and the following exchange happens.
ESTRAGON: What about hanging ourselves?
VLADIMIR: Hmm. It'd give us an erection.
ESTRAGON: (highly excited) An erection!
ESTRAGON: Let's hang ourselves immediately
