Periodically, I'll break into my best Peter Silverman imitation and exclaim "Watch it, buddy!" At some point in the 90s I saw CityTV's Silverman do this during one of his Silverman Helps segments and it stuck.
Thanks to Retrontario, I now have the exact clip. You'll hear it at the 19 second mark of this old CityPulse promo.
Silverman, who was dismissed from CityTV back in 2008, is now 85 years young.
