For some peculiar reason it has become popular of late for people who are posting sarcastic comments on social media insulting someone else's point of view, religious beliefs, or lifestyle to attach a picture of Gene Wilder as Willy Wonka. I usually don't think this is a good idea even on the rare occasions where I have some sympathy for the point that the people who do this are trying to make.

Gene Wilder made a lot of people laugh. He will be missed.
Rest in Peace.
