Too many to list but at the top are:

Diving at the Great Barrier Reef.

Witnessing a Balinese wedding.

Participating in the delivery of my first child.

-in no particular order!

BTW- Stimpy, since you note, "My motto is 'Just Do It'", you may someday receive an unsolicited call from NIKE! And, I'm sorry to have missed you in Manhattan last week!
