I heard this quote recently on some craft show. Don't remember which one exactly but it's not really important. The craft lady said it in this faux russian accent. It sounded so familiar but I couldn't remember where I'd seen/heard it.
It stuck in my mind and a month or so later I seemed to recall where I'd seen it. In the series finale of Quantum Leap titled "Mirror Image" which aired May 5, 1993 the lead character Sam is in a bar talking to an old crippled miner called Stawpah. He's talking about when he was younger and he says "I no always like this. I was big, strong... like bull." I think that is where Push-Pull is referencing because the guy holds up his right hand to rub his forehead while saying this. There is a script online at

It's also quite possible that the quote didn't originate on this episode as elsewhere on the internet some other show/movie in the 60's and possibly Rocky and Bullwinkle are mentioned but I don't believe I saw it there.
