Toonces, I've seen a few oddball things, and I'll relate my experiences. On Christmas Eve, HiTech beats up his dad and gets on his PC, and fires up the magical sleigh and reindeer, flying around saying "ho ho ho mary crismus[sic]". People whine incessantly about the dark, and how much night sucks. They threaten to quit.
Once, they were doing some equipment maintenance or something, and IIRC, there was no score. As a gag, the only plane enabled was the P40-B. The whining surpassed Christmas Eve. They threaten to quit.
During the convention, the RV-8 was enabled, complete with the GUA8a whatever- the giant 30mm rotary cannon of death or something. You'd think HT had personally skewered, barbequed, and consumed someeone's firstborn. They threaten to quit.
Whenever some measure is taken to liven things up a bit, people just start pissing and moaning and acting like the world has ended. There have been other instances I'm sure, but those are the ones that I recall most clearly. The christmas episode repeats annually. It could be fun, but the whiners suck the joy out of it.
