Another guy-in-bar joke:
Young Texan walks into a saloon and says in a drawl, "Uh, hey, barkeep: lemme have a dozen whiskey sours." Bartender starts setting them up and says, "Say, it sounds like you're celebrating something."
"Yup," drawls the young Texan. "Ah jest had me muh first blow-job."
"Well, that's really worth celebrating," says the bartender. "Tell you what--I'll throw in one on the house, make it a baker's dozen."
"Naw," says the young Texan. "If twelve don't get the taste outta mah mouth, I'll jest go home and go to bed."
