Looking for a children’s book my friend remembers from sometime in the mid-70s, so the book could be from that time or earlier.
He can’t remember the specifics of the plot, but the basic structure was that something good would happen, and the main character would say a specific phrase, like “hooray” or maybe “yippee” or something like that, and then something bad would happen, and the character would say “oh no!” or something similar. Then the good/bad cycle would repeat, and the character would use the same two phrases over and over.
I know that’s vague, but the 'Dope has been awesome so many times in the past…
