A mate from work was in pretty much the same situation and somebody advised him the best thing to do was to go to Blackpool towards the end of the season and buy an unwanted donkey off one of the guys who used them for rides on the beach
The journey was a bit of a nightmare with his excited son. Anyway he parked his car in Blackpool and then started to walk to the beach.
As they were at the seaside his lad asked if he could have an ice cream so he bought him an ice cream. His lad then asked could he have some candy floss so he bought some candy floss. His lad then asked if he could have some rock, so he bought him a stick of rock. The good news being that the rock was going to last him some time so he wouldn't be spending any more money on sweet treats
They eventually get to the beach find a bloke with the donkeys and asked if he was prepared to sell one. The donkey owner quite surprisingly said you can actually have one for free. This one here is absolutely useless, so crap in fact that we call it Wanker
So off the beach my friend goes with his son still clinging onto his piece of rock with one hand, whilst holding on to the rope the donkey is attached to with his other
Just off the beach, onto the promenade and a tram rattled past, the donkey bolted away and my friend's son shouted "Wanker's off dad"
His dad replied "look, you've already had candy floss, an ice cream and rock!"
