Please remove the fun tag on Stack Overflow. It's a meta tag and isn't really useful in categorizing questions.
I don't know. I really somehow like those fun questions. I occasionally pass my time at night reading some of them (including that one about the cake for a programmer!)
I'm not supporting them and its a good thing some of those questions have been marked and kept on SO for historical reasons. (I really think the cake question has historical value too, its been deleted I guess)
But I think its what makes us/SO a fun.community
