Oh God please no. I hope I didn't do something that stupid but then I've been pretty absent minded lately. I don't think this is what happened. I think I would have noticed the packaging. I will double check this as well.

I like the plug John_Kunkel posted. I'll grab one.

Facts are stubborn things.
