Whats your most embarrising moment?

I was engaged to my girlfriend, one night after the pictures I took another girl home on my motor bike. While having a big pash with this girl on my stationary M/Bike, a car came along the road. I said to this girl" No worry" they wont know us. WELL, you can imagine my surprise when after the car Had gone past,, I could see the in car was my parents, and my girlfriend. Not nice. !!!!!!!
