Albus Dumbledore
"Ah! Bettie Bott's Every Flavour Beans! I was unfortunate enough in my youth to come across a vomit flavoured one, and since then I'm afraid I've rather lost my liking for them - but I think I'll be safe with a nice toffee, don't you?" Dumbledore took a bean, that looked enough like it should be toffee flavour, and put it in his mouth - nearly choked, and said, "Alas! Ear wax!"
