David Letterman paid tribute to his late mother during her memorial service over the weekend at Second Presbyterian Church in Indianapolis.

The former late night host delivered a powerful and heartbreaking eulogy for Dorothy Mengering, who passed away last week at the age of 95.

'We didn't want for anything because of my mom,' said the funnyman, who spoke of his mother's abilities as both a pie maker and protector.

Recalling one incident during which his mother calmly decapitated a snake she found in the family garden, Letterman said: 'My mother is Grizzly Adams for God's sake.'

The Indianapolis Star reports that the service on Saturday was an intimate gathering of family and friends.

Mengering was known to many fans of Letterman's show thanks to her frequent appearances in cooking segments and as a corespondent during the Olympics.

Letterman said during his eulogy that executives at CBS were so fond of his mother they told him they wanted her back on the program.

'We should have your mother on the show all the time,' Letterman said he was told by executives.

'No, we're serious. People like her better than you.'

Letterman and his sisters Gretchen and Jan also wrote the obituary that ran in The Indianapolis Star following their mother's death last Tuesday.

'Over her lifetime, she reread her well-worn volumes many times, savoring their simple and beautiful language, most recently eight decades after she first turned those pages,' read the obituary.

'Though her quiet life took a detour into the spotlight as she flawlessly stepped into the role of Olympics correspondent and pie baker on her son’s late night television show, she never lost her unassuming demeanor, a perfect foil for his comedy and her full life.'

Her three children were born during her marriage to first husband H. Joe Letterman, a church organist and florist who passed away in 1973.

She married again a decade later to Hans P. Mengering.

Her obituary said of her final moments: 'As Dorothy breathed her last, a brilliant red cardinal landed on a branch outside her window, singing his song.'
