I have'nt come up the thames on a banana boat
"I have'nt come up the thames on a banana boat you know" What does this mean?
Similar, I'm guessing to: I didn't just come to town on a pumpkin (turnip) wagon. I'm not just a farmboy who is new to the big city.
And the same as 'I didn't just float up the Liffey on a lily pad'.DFG
I didn't just fall off the turnip truck.
