Billy Bob and Vern talking one afternoon when Billy Bob tells Vern, "Ya know, I reckon I'm 'bout ready for a vacation. Only this year I'm gonna do it a little different. The last few years, I took your advice about where to go and all."
"Three years ago you said to go to Hawaii. I went to Hawaii and Pauline got pregnant.
"Then two years ago, you told me to go to the Bahamas, and Pauline got pregnant again.
"Last year you suggested Tahiti and darned if Pauline didn't get pregnant again."
Vern asks Billy Bob, "So, what you gonna do this year that's different?"
Billy Bob says, "This year I'm taking Pauline with me."
