From a mid-20th century instructional manual, McDonald Hastings, How to Shoot Straight:

Notice that when you are in bad form--I hardly care to recommend this, I simply state the fact--you will sometimes find that you shoot straighter, after you have drowned your sorrow in the middle of the day, than you did when you believed that you were on your toes in the morning.

p. 82 First American Edition, 1970.

Of course, Hastings also recommended, in describing the tempo that is the key to successful wingshooting, that you should mount the gun as you would mount a woman, "start gentle, finish hard". (p. 54).

Anyone care to comment on mixing sex and alcohol?
