David Letterman, who retired earlier this year, made a surprise appearance at a Steve Martin/Martin Short show in San Antonio, Texas, using his time to unveil a Top 10 List that went after presidential candidate Donald Trump.
"I was complacent. I was satisfied. I was content. And then a couple of days ago Donald Trump said he was running for president. I have made the biggest mistake of my life."
To the audience's roars of approval, Dave read off zingers such as, "Donald Trump looks like the guy in the lifeboat with the women and children."
