Late-night talk host David Letterman has made hundreds of millions making fun of politicians who are caught up in major scandals, especially sexual blunders. And judging by his continued attacks against Sarah Palin, one may surmise he will not change a comedic formula that's worked in garnering him millions of fans and even more millions of dollars.

It's anyone's guess whether or not Letterman's showbiz career will be damaged by his recent admission that he has had sex with women who worked for him. Letterman is a husband and father, but that doesn't seem to bother many of his fans. It wouldn't surprise me if his Nielson ratings actually climb, since far too many Americans are willing to reward bad behavior. Big difference between Letterman and those he has ridiculed is that the butts of his jokes haven't taken glee in his sexual exploits being exposed in public.

Personally, in that name of decency, I believe David Letterman should resign. But that's just my opinion. And in keeping with a Letterman trademark comedy routine, here are my Top Ten Reasons Why David Letterman Should Resign:

Number 10: Former President Bill Clinton. Letterman made a career out of telling President Bill Clinton-Monica Lewinsky jokes.

Number 9: Former Presidential candidate John Edwards recently went through his own sex scandal. Letterman placed him No. 1 on Letterman's "Top Ten Signs Barack Obama Is Overconfident: Been cruising for chicks with John Edwards."

Number 8: South Carolina Governor Mark Sanford. "Both my thoughts and my prayers are with him," said South Carolina Governor Mark Sanford Tuesday after a speaking engagement at a Rotary Club meeting in Easley, S.C. One of many jokes Letterman told was the governor "didn't really enjoy this year's Fourth of July. He left his favorite firecracker in Argentina."

Number 7: Former Alaska Gov. Sarah Palin's 14 year-old-daughter was viciously attacked by Letterman. I will not even repeat what he said. Continued...
