A couple of guys were having a drink in a pub when one sees a motor home come into the parking lot. "look at that great looking van" paddy says. His friend says, " I have one of those". Paddy asks if they could go for a spin so they go to get the motor home. After a few miles his friend stops. "What's the trouble" he asks. "Well the tunnel says 11 ft 6 inches only and my van is 13 feet" Paddy says "Oh go for it, there are no police around". "OK, I'll give it a go"
