Fun fact, hot dogs were the last form of animal flesh I could eat. Back when my sister was a toddler she ate with her entire head. It's really a miracle she didn't starve to death, considering how little food actually made it into her mouth. I was a weird enough kid as it was, I had sensory integration disorder which apparently was really bad back then but with years of therapy or some nonsense I'm completely over whatever issues there were. One of the side effects of my weirdness was that if I saw my sister eat something that wasn't impossible to make a mess with, I could never eat it again. I still can't. So anyway, pretty soon the only things I were able to eat were dry, didn't require silverware, and couldn't be smeared all over my sister's face. Hot dogs somehow ended up being the only meat I could still eat until one day I imagined a pig and suddenly that was off the list too. I really was a fucked up kid.
I'm almost over it though. I can eat fish but I usually don't, the last time I ate red meat I didn't like it but I didn't throw up either. Like I said, years of therapy banished most of the weirdness of my childhood and now it's just the matter of breaking habits that I've been set in for my entire life. I still probably couldn't eat hot dogs though. Aside from the whole "Pulverized pig meat wrapped in pig intestine" thing, I've seen how brats get revenge. I remember brats'n'mets day in second grade. I can still hear the screams of my friends, their tracheas suddenly inundated by boiling pig juice. It was like Vietnam.
EDIT: Okay, that's an exaggeration. It was one kid, his name was Casey. He took a bite out of a brat and got blasted with said boiling pig juice. He gasped and we laughed at him. It was sort of like Vietnam, I guess. We were outside, and Vietnam was outside.
