1) "Wow Mom, these are just like the games I played on my computer, when did they start making them for real"?
(I was respectful in my answer for "enlightenment" although I felt quite bad at the time because this was the late 90s after "Black Friday, and Stern was not yet making games again)
2) "Your a little on the eccentric side, aren't you"?
(They then played part of my collection, and then changed their mind, "here's your sign")
3) "Sorry, I just don't understand how a person can have these things in a bedroom, this is just too much for me".
(A woman I was dating, but not for long)
(It was a spare bedroom, folks...just so you know...gotcha)
4) "Do you play your machines"?
(This was for insurance purposes)
"Yes, of course, I do".
"Well, we cannot insure them if you play and use them".
"What"? "I need an explanation here".
"What the hell is the difference between a pinball machine and a classic car, guitar, or motorcycle"?
"I mean people drive and use these items too".
"Well, we understand that, but we have no idea what they would be worth for replacement values, who exactly appraises them"?
"I DO, welcome to my world, feel free to contact me anytime".
(I took care of this problem with Lloyds of London, solved)
5) "Does this thing run completely on batteries"?
(Even though they were looking at the power cord)
6) "How do you start this damn thing, this is TOO complex for me"!
7) "What is happening, did I win, do I get to keep one of the balls as a prize"?
(Balls were draining for reset at the end of the game, and the player was mashing the flipper buttons that were not responding)
"What the #$@% was that, did I break something"?
(Player jumps 3 feet in the air after the knocker cracks after a free game match)
9) "You really need to get a girlfriend".
(I explained I was already married, my wife was out of town at the time)
Maybe more later...
