Just wanted to say, I adore your site. Anyway, my personal childhood trauma occurred in 1995 (I was 6-years-old then) during the Superbowl. I'm there with my family, eating some chips, enjoying the game and commercials, until I saw something that screwed me up but good—Pepsi's 1995 "Sucked In" commercial.
It's the one where the kid (wearing a sailor hat, no less) is slurping his Pepsi on the beach. He's slurping and slurping, and finally overdoes it and gets sucked into the bottle from his straw, leaving him trapped inside.
Alone.
I was scared to watch another commercial for the next two or three years, and although I'm a huge horror fan now, I refuse to give that commercial another viewing.
