I think "I'm at my wit's end" is correct. Are you saying there's a place called Wick?

The actual whole quote as I always knew it is

LOL, the James Brown quote in your sig is wrong- it's "I don't know karate, but I do know KA-RAZY!"
No, you're wrong. Do a search, there was a multi-page debate on this subject a few years ago.
And since you're being so persnickety, your handle is wrong. It's either Holmes or Homie. Choose wisely.
