A very old joke
An old man was riding his bike along the A1 when his chain broke, he couldn’t repair it and was miles from anywhere, so he started pushing his bike on his long trip to civilisation.
It starts raining hard and the poor old man struggles against the wind and rain, then a Ferrari pulls up and a concerned young man asks if he can help, when he realises that the bike isn’t repairable and won’t fit in his car he offers to tow the old man to the next town.
The young man promises to drive slowly but tells the old man to ring his bell if the tow becomes too fast.
Everything is fine for the first couple of miles as the tow proceeds at a comfortable 20mph then a Lamborghini overtakes the old man and makes a rude gesture to the driver of the Ferrari.
The Lamborghini takes off like a rocket with the Ferrari in hot pursuit.
Meanwhile a couple of miles down the road a Police car sits quietly in a layby when the Lamborghini flashes past, as the Police car starts the Ferrari roars past.
“Did you see that Sarge” says one of the officers “they must be doing 120” the Sergeant replies “Yes but what got me was the old guy on the bike ringing his bell and trying to pass the pair of them”
