"I appreciate this from the bottom of my heart and I appreciate you all coming here in the rain," Sales, who was seated in a wheelchair, said Friday.
The rain forced the ceremony to be held inside the Hollywood Roosevelt Hotel, with Hollywood's honorary mayor, Johnny Grant, setting up the 79-year-old comic's classic schtick.
"Frank Sinatra, Sammy Davis Jr. had pies thrown in their face by Soupy Sales and I want to belong to that club," Grant said. He then got down within Sales' reach and took a pie in the face.
The star was the walk's 2,274th. Celebrities attending included actor Peter Marshall and actress Nancy Allen.
Sales, whose given name is Milton Supman, was born in North Carolina. He got his start as a radio scriptwriter and standup comic, going on to host immensely popular local children's shows in Cincinnati, Detroit, New York and Los Angeles. He also has made guest appearances on numerous TV shows, occasionally appeared in films and twice had hit records, with the novelty songs "The Mouse" and "Spy With a Pie."
Besides throwing cream pies, Sales also takes them in the face. He once estimated he had been hit 25,000 times.
