I had two "moments": As a teenager first time I got the special lights lit on 4 Square at the local roller rink (yes I am that old) and hit them repeatedly - that pop, pop, pop of the knocker. Wow.

Second time: after only occasional brushes with pinball at bars or pizza places through my adult life, visited my new wife's godson 6 years ago who had a house full of games. Oh crap, you can actually own pinball machines??????? My first was a 4 Square he helped me find 2 days later. Have 15 in the collection now and have had 48 total.
