He told me to use my artificial Christmas tree as a buttplug!!! Is this legal?

LOL! Well, I oper on a friendly network. I do suggest you consider Starbuck's advice though. Take your mates with you too, it's obvious that they just want to make life hard for you, it being their server, well, there's no law against it - IRC is a privilege. grin

As for the comment you quoted, well, I suppose that oper has probably done the same thing himself and feels embarrassed about being the only one to try it so far.
