Did you ever have a pogo stick?
They had a brief resurgence of popularity in the 70s and all my friends were pogoing and I got one. I couldn’t even do one pogo. To make matters worse, I tried and tired and failed and failed. Then my mother got on it and was pogoing up and down and she was over 50 at the time.
I just couldn’t get that darn thing to work for me ERRRRRRR
