jumped like he was on pogo-sticks (one for the oldies),
Indeed... here's one of my claims to fame...
I once pogoed from my own house to my cousins' house (about a mile away). This wasn't just a simple pogo journey. There were:
17 steps from my front door to the pavement
a hill up to the top of my road
a series of SEVEN flights of stairs from there to the next road below - average, say, seven stairs per flight
then the main part of the journey down dale and up hill
Finally...
My cousins lived in the top floor of a block of flats (no lift) and I pogoed all the way up.
A couple of hours later, I pogoed all the way back again.
And all without coming off once.
I must have been about 12 or 13 at the time and was already the local skipping rope champion, better than the best of the girls and miles ahead of any of the boys. I could easily skip for over an hour in those days so pogoing seemed a doddle by comparison.
