It's unfortunate that common courtesy isn't all too common in general life.

For example, it is common courtesy not to put your bare feet on someone else's armrest, but a passenger on one of the Walker Twins' flights, clearly did not get that memo.

The twin with the offender had to do something to get revenge.

He slyly poured the water on the person's foot, causing them to withdraw.

People certainly had other ideas of how the man could have really handled the errant foot, ranging from the slightly more mischievous to the outright vicious.

Lack of consideration on forms of mass transportation runs rampant, as anybody who has ever been on a plane knows.

Whether you're next to a loud snorer, or a crying baby, or just someone who does not know how to mind their own space, you really have contemplated getting revenge in a similar fashion.

Keep your feet to yourself, readers.

Else you might find them wetter than when you started.
