Trying not to get angry at co-worker

[RockyR]

Formal complaints get too 'sticky' down the road and invite retribution or a revocation of your kilt wearing priveledges.

I would look him dead in the eye and calmly explain: "I'm all for having fun, but this is really not funny and in fact, it's quite insulting. I'd appreciate it if you acted like an adult in my presence."

No need to sink to his level and insult his choice of clothing (or mate, or his mother... hahaha). Just take the high road, politely (but firmly) explain that he's acting like a child and end the conversation.



EDIT: I just noticed that this was done in front of students. I RE-AFFIRM my suggestion. Politely but firmly let him know his behavior / comments are juvenile and unacceptable.
