All good things must come to an end, so they say, but that doesn't mean you can't go out in a roar of laughter.

Such was the night of Wednesday, May 20th when the legendary David Letterman said his final farewell to late night TV in a bittersweet finale filled with flashbacks, video snippets and A-list celebrities, comedians, the Foo Fighters and even five presidents who helped him close out over three decades of quirky comedy, wit and, grace.

Dubbed "TV's Biggest Curmudgeon" by NPR, Letterman kept it light and not too mushy as he delivered his material in his own way -- just keeping it real, a trait for which he's been admired.

In a classic spin of Letterman's famous "Late Show" Top Ten, Bill Murray, Tina Fey, Chris Rock, Peyton Manning, Julia Louis-Dreyfus, Jim Carrey, Jerry Seinfeld, Steve Martin, Barbara Walters and Alec Baldwin gave their hilarious takes on "Things I've Always Wanted to Say to Dave."

The jokes were of course hysterical and packed a punch, especially one delivered by Rock who said: "I'm just glad your show is being given to another white guy," Rock joked. (Stephen Colbert will take the reins from Letterman in September.)

In addition to giving Letterman a hard time, Louis-Dreyfus went below the belt in her Top Ten listing, saying: "Thanks for letting me take part in another hugely disappointing series finale."

While the joke brought huge laughs, especially from Carrey and Martin, Seinfeld didn't look too thrilled, with a bruised ego saying "Really?" to his former co-star and pal, before giving in and smiling.

Letterman insisted that he didn't have anything to do with either.

Needless to say, the energy was contagious that night as with many other nights where Letterman's unique approach towards interviewing often brought uncomfortable, quirky or weird laughs from his subjects and the audience. He also had a genuine chemistry with many A-listers, including famous Latin actresses who were guests on his show.

Salma Hayek, who also has a great sense of humor that gelled nicely with Letterman's, visited the show several times over the years.

During one visit, Hayek unexpectedly raved about her love for bugs, reportedly saying: "We eat bugs, but we don't eat horses," she joked. "And we have many recipes for some of them."

During her most recent visit last July, Letterman reportedly got the Mexican actress to sing the U.S. national anthem as well as hum a part of the Mexican national anthem.

In September 2009, Letterman invited Colombia's most famous stars and stunning beauties, singer-songwriter Shakira, who rocked her hit "Loca," and "Modern Family's" Sofia Vergara who raved about her country's beauty.

In August of 2010, the former Miss Universe Ximena Navarrete of Mexico was a guest on the "Late Show." The Mexican beauty also gave her spin on the famous Top Ten countdown, "Top Ten Ways Miss Universe Plans to Make the World a Better Place."

Seems like there could be yet another Top Ten in honor of Letterman's 33-year career in the TV biz with "Top Ten Ways David Letterman Made Late Night TV Worth Watching."
