Major Spoilers Question of the Day: Unexpectedly Frightening Edition

I admit it: As a child, I was traumatized by Twinkie The KId.  The idea of a creature of living spongecake is more than a little terrifying, especially given that his JOB was to get people to purchase and eat others like him.  Fruit Pie the Magician could use his sorcery to escape a Donner Party situation and King Ding-Dong…  Well, he kinda deserved to be eaten, but Twinkie was just a cowboy, with simple cowboy needs.  Heck, he might not even realize what was going on with the TV cameras, making for an unexpectedly frightening commercial and leading us to today’s in-honor-of-Halloween query…

The MS-QOTD (pronounced, as always, “misquoted”) was also a little freaked out by Timer, who may or may not have been made of living cheese, asking: What commercial did and/or do you find most unexpectedly frightening?
