The pictures come from a article written by Bert Kay. Unfortuantly Bert died a few years back according to the link at the bottom.  The man making the drink in the pics died as well. 
The whole thing seems kinda sad.  Its weird seeing articles written by people that are now gone.

This is my little homage to Bert and his dad, and the drink that lives on--The Wiskey Sour.

Sort of like one of those annoying mass emails you get, but actually funny.

A survivalist guide

CROP DUSTING:
When farting, you walk briskly around the office so the smell is not in your area and everyone else gets a whiff but doesn't know where it came from.
Be careful when you do this. Do not stop until the full fart has been expelled. Walk an extra 30 feet to make sure the smell has left your pants.

FLY BY:
This is the act of scouting out a bathroom before pooping.
Walk in and check for other poopers.
If there are others in the bathroom, leave and come back again.
Be careful not to become a FREQUENT FLYER.
People may become suspicious if they catch you constantly going into the bathroom.


ESCAPEE:
This is a fart that slips out while taking a leak at the urinal or forcing a poop in a stall. This is usually accompanied by a sudden wave of embarrassment.
If you release an escapee, do not acknowledge it .
Pretend it did not happen. If you are standing next to the farter in the urinal, pretend you did not hear it.

No one likes an Escapee. It is uncomfortable for all involved.
Making a joke or laughing makes both parties feel uneasy.


JAILBREAK:
When forcing a poop, several farts slip out at a machine gun pace.
This is usually a side effect of diarrhea or a hangover.
If this should happen, do not panic ! Remain in the stall until everyone has
left the bathroom to spare everyone the awkwardness of what just occurred.
