Face the facts... the inlaws are a pain in the ass, you deserved to burn off a little steam before the big day. Cigars & Stripes style!
Yeah that's right... you go ahead and fall asleep after dinner..in front of the whole family while yer' mom and grandma gather round and say nice things. Like... "He works soooo... hard, my lil' Johnny had a paper route at the age of 11 you know", and if your lucky they might even throw in a couple of ... "Don't you wake your fathers!"
Enjoy this time because it will all come to a screachin' halt, yer' wife knows damm well yer hanging like a dogg. Just cross yer' fingers that you dont blast out a leftover beer fart and by all means, keep yer hand out of yer pants, because when the nights over you will have no choice but to face your wife and the loooonnnggg ride home... It's go time, baby... you drink up and remember... you da' man of the house!
