Why I Don't Work Well With Others

I was told this in all seriousness last Thursday:

I don't think it matters that our site doesn't look good in Firefox. I've looked at other big sites that don't look good in Firefox and we're no worse. Is it even possible to make a site that looks good in all browsers? I don't think it is.

All I could do was rub my neck and say, "No, actually it is."

*sigh*
