Stu Francis has warned new Crackerjack hosts Sam Nixon and Mark Rhodes to stay away from his catchphrases.
Presenting duo Sam, 32, and Mark, 37, are set to front a reboot of the classic kids TV series next year.
However, 68-year-old comic Stu, who was known for lines such as "Ooh, I could crush a grape" when he presented the programme from 1979 until 1984, thinks it would be a "backwards step" if they mimicked his signature phrases.
He told The Sun's Bizarre TV column: "They're not my copy-right as such, but I would like to think they've got more going for them than to do somebody else's catchphrases.
"That doesn't gel at all. That'd be like me going out on TV next week and saying, 'Nice to see you, to see you nice'. It's just not right.
"Everybody in the business associates those catchphrases with me. If they started doing that they'd be taking a backwards step."
When BBC chiefs announced the programme was being rebooted and modernised, they confirmed the game Double or Drop - in which young audience members are chosen to answer questions and go head-to-head to win prizes or a consolation cabbage if they give an incorrect answer - will be making a comeback in the new show.
I would like to think they've got more going for them than to do somebody else's catchphrases.
However, Stu thinks a fresher format might be better for today's audiences.
Stu added that he doesn't know if children today will be as interested in the challenge because it is dated.
He said he thinks it is "too slow" for modern audiences.
Crackerjack will return to CBBC and BBC Red Button next year.
