This question already has an answer here:
This edit was made to my answer, which I have since rolled back. When I saw it, I was offended by it - yes, it was a joke, but it didn't take away from the quality of the answer at all - it was in its own paragraph at the bottom of the answer!
The joke wasn't offensive in any way, and it is highly unlikely that anyone would attempt to call the fake phone number in the answer, so how was it a "bad joke"?
I feel like people take this site way too seriously sometimes - so, should by we allow these types of small, amusing parts in answers?
