how do you spell "conniption?"

So, I was with my friend LJ Daimel today.
We were both in like the 99th percentile for spelling as children.
She used the word "conniption" in conversation and we got to wondering, how do you spell "conniption?"
We both spelled it out in unison, spelling bee style:

conniption. c-o-n-n-i-p-t-i-o-n. conniption.

Later we googled it and discovered we both were correct with our spelling.

How do you like that?
