When Billy Bob tells Lester, "Ya know, I reckon I'm about ready
for a vacation. Only this year I'm gonna do it a little
different. 

The last few years, I took your suggestions as to
where to go. 

Three years ago you said to go to Hawaii. I went
to Hawaii and Marie got pregnant. 

Then two years ago, you told me to go to the Bahamas, 
and Marie got pregnant again. 

Last year you suggested Tahiti and darned if Marie didn't get pregnant
again."

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

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