David Letterman: Top Ten Racer

David Letterman

David Letterman plans to literally race through his retirement!

The legendary funnyman is seriously thinking about following his career in show business with a stint as a race car driver – but don’t tell his wife!

“It’s something he’s always toyed with,” an insider told The National ENQUIRER, citing Dave’s minority ownership stake in a racing team.

“Dave’s always been a huge Indy car fanatic, and grew up just blocks from the Indianapolis Motor Speedway. The only problem is he’s not a good enough driver – yet!”

Right after ending his long career with “Late Show,” Dave flew all the way from New York City to his hometown of Indianapolis to see the race in person.

The 68-year-old retiree followed that by taking his son, Harry, on family outings to races around the country. But his wife, Regina, has a slower retirement in mind!

Our insider spilled: “If Regina had even an inkling of what he had in mind, she would flip out!”
