Always make sure you check your destination carefully too. About 10 years ago a group of us rode to the Le Mans bike 24hr and we stopped in Paris on the way back. We decided to go and have a look at Notre Dame and so the one guy in the group who had a sat nav duly punched it in. 35 minutes later, we arrived at a nondescript church built c.1950 somewhere in the suburbs because the daft C U Next Tuesday obviously hadn't realised that there are probably dozens of churches called Notre Dame (Our Lady) in any French city with a significant Catholic population.
Not many men could get away with calling their wife's backside a whopper, but context saves you there. At the other end of the meteorological spectrum, I once pulled over on a ride in the depth of winter as I thought I heard a police siren; it was actually my then-girlfriend, wailing with hypothermia.
