AskMe: How to become an eccentric (or just look like one)

Suggest eccentricities for me to adopt | Ask MetaFilter

From a fun AskMe thread:

In my quest to become more distinctive, I’m looking for suggestions of harmless eccentricities to adopt. Who better than the MeFi hive mind to provide them? Anecdotes of eccentric folk you’ve known in the past welcome.

This reminds me of that stage where teenage girls randomly start to affect a terrible british accent, or when college freshmen suddenly stop wearing shoes and take up raw foods and the shakuhachi. Of course, this is not to say that I haven’t had ideas of my own.

’Fess up: what was your goofiest affectation and what made you stop it?

Clarification (2006-07-15 10:20:20): The “In my quest…” portion above is a quotation from the link that is referenced; it’s not actually me asking for help to (God forbid) become more eccentric. This confused some people, and, well, I regret your confusion if you have any and hope this clarification helps. – The Management

My wife knew a German...

My wife knew a German girl who kept a peach pit (stone) in her mouth at all times. The same one. All the time.

Last we saw her she was on her third, having lost the previous two accidentally. I can’t recall if she had swallowed them or spit them out by accident, but quite different eccentric, I believe.
