What's the worst tantrum your toddler ever had?

I have a 4 year old and a 15 month old. My 4 year old is vey affectionate and laid back and I can't remember him having major tantrums. My 15 month old on the other hand is very smart and a fighter. We were in church on Sunday and he had the worst tantrum. He was on the floor screeming and kicking the chairs in the middle of the sermon. It was not pretty folks. All because he wanted to walk down the middle of the church floor and we weren't having it. We just had to leave.
