Billy Bob and Bubba were talking one afternoon when Billy Bob tells Bubba, "Ya know, I reckon I'm about ready for a vacation. Only this year I'm gonna do it a little different. Last three years, I took your advice as to where to go."

"Three years ago you said to go to Hawaii. I went to Hawaii and Betty Lou got pregnant."

"Two years ago, you told me to go to the Bahamas, and Betty Lou got pregnant again."

"Last year you suggested Tahiti and darn it if Betty Lou didn't get pregnant again."

Bubba asks Billy Bob, "So, what you gonna do this year that's different?"

Billy Bob says, "This year I'm taking Betty Lou with me."
