OK. Well, I didn't get the dozens and dozens of guesses that others did with this game, but it was fun anyway.
The answer is #2.
Something similar to this did actually happen to my buddies J and D, but I was not along for the ride. Instead, if I remember my ancient history correctly, I was helping another friend with his Eagle Scout service project when the whole affair went down. Being anxiously engaged in a good cause has kept me out of trouble more than once.
FYI, this is a PBY Catalina
As for #1, the haunted house story was pretty much just as I described it. I personally never saw or experienced anything, and often spent hours alone in the house by myself after dark (reading like a true geek). But whether or not the house was truly haunted, most people believed it was.
#3 - what can I say? Looking back, I still can't believe I thought concocting a pretend girlfriend would make for a funny joke. I guess everyone does at least something embarrassing when they're 16.
