I'm writing a fictional war story where one side sets up a website that allows foreigners to donate to the war effort. In exchange for their donation, a message of their choice will be written on the side of an artillery shell and they will receive a picture of the shell just before it was fired. 

Give me some short lines that a foreigner might find funny to see written on the side of a shell.
