I don't know how dumb this is but it was a memorable.
We were flying from ABQ to Pheonix Skyharbor in the late morning. The wife and I were making one of our twice yearly cross country trips, this time the destination was San Diego. The weather was severe clear with unlimited visability. The day before the winds were blowing at 40 knots, so the trip into ABQ was pretty rough and to wake to such a nice day was great, no wind, temperature in the 70's. The climbout from ABQ was smooth and relaxing in the skyhawk. I put the plane in a slow climb up to a few thousand feet above the high desert floor. About an hour into the flight a small developing thunderhead is forming ahead of us. In ten mins it had grown 5 fold and the base was spreading across the floor of the desert. I started to deviate to the north, only to find it spreading faster then I could fly. The cloud had not formed an anvil top, so I decided to head under the base of the cloud. By Nebraska standards (home state) this was a small cumulus cloud, it had no virga, and no lightening.
We were just about back in the sun on the back side of the cloud when an up draft caught us and we headed up at 500 feet a min. A few seconds later we were inside of the cloud and climbing even faster, The altimeter is showing us climbing throught 14,000 feet and eccelerating up, now the VSI is showing 2000 feet per min up. As we past 15,000 feet, I expected to come out of the up draft, but we were still climbing. At 16, ooo feet my wife decided to take a nap. I made the decision to pull the power to idle and put the aircraft into a 30 degree nose dive and then I set the auto pilot to heading to maintain wings level just in case I went to sleep, At 17,000 feet, the VSI was topped out at over 2,000 feet per min. At 17,400 feet we came out of the up draft like we had been pushed off the side of a skyscraper. As I was desending my wife woke up and asked how much longer to Pheonix. Maybe both of us had been flying in small planes to long, but it didn't get either of us that excited.
I sorry that this isn't as good as all stories about misplaced keys, but I tried.
