Which of my other 5503 posts should I refer you to?
other than that... here are a couple:
I was sitting downstairs at my parents' house about maybe 25 years ago, and my sister and her friend (who was overweight) were sitting upstairs. It was during Grenada, and the news was covering an anti-war rally. I was with my dad and my brother, and didn't know the girls were up there. So I said, nice and loud... "they should have an anti-fat rally..."
On another occasion, me and my friends in college (about 20 years old) were all being immature and talking in cheap, phony chinese accents.
In the food court we had a Mark Pi's Express. I walked up to the counter one day, and without thinking said "ahahaha, prease to have armond boneress chicken!". They stared at me, took my money and prepared my food. Luckily I could see them preparing it...
And a third that I just remembered... I've been working for the same guy for about 6 years now. 5 years ago, as Halloween was coming up, he asked what I thought he should dress up as for the office. Being a lifelong fan of pirates, I suggested Long John Silver. Come to find out he lost his leg to cancer when he was 21. One of his legs is a prosthetic. I never guessed because he's on the company softball team.
