Blind date - nope

Ask out or at least introduce yourself to a stranger - I introduce myself to quite a few strangers, but haven't asked any out that I remember. It's been a long time- I usually got to know someone first.

Start a cult (In case jay pops in) - Sort of. We had a joke cult in junior high. I was The Poop, the equivalent of the Pope

Join a group or club - Yep- joined the Robotech Fan Ckub back as a lad in the 80s. Joined the Star Wars fan club in the late 90s/00s and still have a bunch of old SW:Insider mags with articles on the upcoming prequel trilogy

change careers - Same firm, but switched from a internal consulting job to my current job.

Invent something - I have invented a number of alcoholic beverages in my time, like the Car Accident (w/ Ambulance chaser- I don't remember everything that went into this but it was delicious), and the Axis Powers (jaeger and sambuca in a shot).

Create a new recipe - Do this all the time. Last night I did my famous Thai/Korean fusion pork ribs. Mix of spices for the rub, plus green Thai curry paste. Slow cook the ribs, then grill them with bulgogi Korean bbq sauce. Super tender ribs with sweet, savory, and spicy. They are fucking awesome.

Enter a contest - I am sure I have but can't think of any interesting ones.

Go to a church, school, or or community sponsored event - I guess I've been to a few, but again, what exactly do we mean here?

Knock on doors to meet your neighbors - Sort of run into them out and about. When the synagogue up the street got a new rabbi awhi;le back, we started seeing this woman with a yarmulke running around and surmised it was her, so we ambushed her on the street and we've been friends ever since. We're the crazy Gentiles she won't let come back to Passover Seder.
