This is my own personal all-time favourite compliment.

Many years ago, I was drafted in by a friend who belonged to an amateur dramatic and operatic society for their upcoming performance of 'Bless the Bride' - they needed a second footman for the drawing room scenes, as well as an additional male voice to add a bit more weight to the chorus songs. The acting required of me as a footman was mainly standing still at the back of the stage, and occasionally opening the door for one of the principals when they left the scene.

Another friend came along to watch one of the performances. When I met him for drink afterwards, he was obviously trying to think of some compliment he could give me; and eventually, he came up with:

"I thought you were the better of the two footmen."
