What Should I Wear?

A trapper was in the middle of nowhere and stumbled upon a general store and went in.  As the trapper was looking around, the storekeeper said, “I’m havin’ a party tonight, and your invited!”.
“Well that’s mighty nice of you.  Thank you”, replied the trapper.
“But I gotta warn ya, there’s gonna be drinkin’”, said the storekeeper.
“What kind a party would it be without drinking”, answered the trapper.
“And I gotta warn ya, there’s probly goin’  to be fightin’”, said the storekeeper.
“This is some kind of wild party you’re throwing!  I’ll try to stay out of trouble.”
“And I gotta tell ya there’s gonna be foolin’ aroun’ if you know what I mean.”
“I want to thank you again for inviting me.  What should I wear?”
“It don’t matter, it’s just gonna be you ‘n me.”
