Make use of memes. 9GAG is a great start place.
Make exceptional use of idioms, etc. For example,
When dining out in a restaurant, take a sip of the water, act unimpressed and say, "taste like water."
If you are Greek, upon hearing any non-English speech (perhaps public announcements in a plane?), say, "it's all Greek to me."
Note: It also worked for me when I said "sounds like Chinese to me," so I guess you can improvise a bit.
Not Greek nor Chinese? Consult this wonderful graph.
Blame your (potentially imaginary) cat when you mistakenly sent a garbage message to someone rubbing over your keyboard:
Sorry about that message; My cat thought it funny to roll over my keyboard, and she's not even sorry.
If you can't escape from a undesirable situation, try changing your perspective.

When in a contemporary art museum, if you are having a hard time making sense out of the abstract paintings, try imagining them as slide deck backgrounds.
Try answering these questions:
What arrangement of visual objects would this painting suitable for? A title slide? A text-and-image slide? A quotation slide?
What can I put each of the visual objects?
Which paintings can be used together as a template for a whole deck? A useful template for slide decks should define a style for most of the popular arrangements, such as title slide, content slide, quotation slide, and half-and-half slide. Focus on their visual coherence/consistency.
