At this one competition, I was walking in the hall, heading to lunch...and these two girls come up to me and both want a high five from me. We'll call them Thing 1 and Thing 2. Thing 1 gives me a high five and starts to run away, then Thing 2 gives me a high five and starts to run away too; at this, Thing 1 doubles back and says "I get more high fives than you!" and high fives me again, then runs away. Thing 2 says "No you don't!" and runs back and gives me another high five and runs away. They keep doing this loop thing for about 5 times, until finally Thing 1, after high fiving me, folds my hands and says "No more high fives." Then they both run off.
And a guy from another school saw the entire thing, when it was over he came up to me and was like "What was that about?" I explained what happened to him and, well, he just said "This is Science Olympiad. Weird pigeon happens."
