Crazy post card – images need context

Ok, so this is a old vintage crazy graphic. Not sure what to make of it. Even though a picture is worth a thousand words, sometimes its just a few WORDS that really shed light to the context.
Here are some captions that change the thought:
“i wish this babysitter would go home”
“don’t move, let me shoot that fly off your shoulder”
“there’s a really bad man behind you wanting to steal your rasta hat, i gotchya back”
any more???
everything about this is so wrong! I wonder the concept behind the photo shoot.
