Well, it didn't seem particularly *funny* at the time... but anyway
My test for shodan started off with me and a couple of friends sitting in the parking lot at Bethony sensei's dojo, having gotten there much too early and with way too much time on our hands. We had driven down together, ostensibly for mutual support, but, of course all we did was proceed to worry the s__t out of one another during the course of the drive. Now waiting in the lot, we got to see the other candidates as they drove up. One of my friends, a serious weight lifter himself, commented on one of the guys who had just gotten out of his car "good god, look at that guy, his calves are the size of my thighs!"
After completing most of the test, it was time for sparring (why do the "funniest" stories always end up here?) segment. I lined up, and got paired off with a guy who was about my size. We talked for a bit, and I began to relax - neither of us was out for blood - we just wanted to look good, and pass! Just before we started, Bethony sensei said "no, no, no, you two can't spar, you work out together all the time!" Two things occured to me in short order: First, that the only way sensei could know this was if they were his students (noted for being fierce competitors), and second, that although my current partner was standing to my right, standing to my left was the behemoth - one of sensei's students! After we were rearranged to sensei's liking, I of course was matched up with the giant, although the match was memorable only in the fact that afterward, my friends said comforting things like "wow, I'm surprised you're still alive..."
All this however was not the most memorable piece for me. At the end of the test, we all lined up. Absent was one of my friends - he had been "tapped" on the shoulder and was now in the back room hearing that he had failed. Bethony sensei now began reading off the names, and one at a time, students began to go up and be congratulated. I stood and waited for my name to be called, and waited, and waited. I thought "maybe they're not going alphabetically," then "maybe they forgot to pull me aside," and finally even "could I possibly have made 'best of test'" (the last candidate announced). Well they announced best of test, everyone had a final round of applause, and bowed out. I was stunned. I found Paul Giella (sempai in my dojo, and a test board member), and asked "Did I fail?" He said, no, and proceeded to talk with Bethony sensei, who, as everyone was leaving, loudly announced "oh, also, Greg Postal, shodan." Better late then never! (But man was I sweating!)
The other, "funnier" test experience I had was at my nidan test, also in Brockton. Again, we had finished everything but the sparring, when Canna sensei made an impassioned speech about karate, the importance of sparring etc. What made the biggest impression on me at the time, (sorry, sensei) was the story he told about the fact that most of the fatalities in car accidents he had investigated resulted from ruptured bladders spilling toxins into the bloodstream. He concluded this by saying, "so what I'm trying to get at is: make sure you always use the bathroom before you spar." After everyone had a chuckle over that, there was, predictably, a mass exodus toward the bathroom. Unfortunately, the joke was on us as Bethony sensei shouted, "Okay everyone, gear up! let's go, right now, we want to get out of here today!" Maybe someone got to get to the john before they sparred, but I didn't, although you can be damn sure I thought about it throughout my match that day!
