An old Scottish woman told me that once when I was hiring a kilt for a wedding I was a groomsman at. Of course I followed her advice and during the reception, while quite drunk, the front of my kilt got snagged up in my sporrin. Quite embarrassing but it did attract a cute girl that I went home with that night.
So the lesson? No underpants in the presence of cute girls.
