Propose ludicrous suggestions to your friends and those around you with no provocation. Such as, "What if we all took off our shoes and put them in a pile right over there, just for about twenty or thirty minutes." Do not offer explanations. End all of your ideas abruptly, without seeking input from your listener. A few moments after your proposal, regardless of the reaction it received, cease paying attention. You could also possibly walk away, though that verges more on being rude than being awkward.
