(1) A person belonging to an ethnic group whose members are commonly
considered to have certain stereotypical mannerisms met another
person belonging to a different ethnic group with a different set
of imputed stereotypical mannerisms. The first person acted in
a manner consistent with the stereotypes associated with his ethnic
group, and proceeded to make a remark which might be considered
to establish conclusively his membership in that group, whereupon his
companion proceeded to make a remark with a double meaning, the first
meaning of which could be interpreted to indicate his agreement with
his companion, but the other meaning of which serves to corroborate his
membership in his particular ethnic group. The first person took
offense at his remark, and reacted in a stereotypical way!

(2) Q: How many people belonging to a certain ethnic group does it take
to perform a particular menial activity?

A: A finite positive integer. One to perform the activity, and the
rest to behave in a manner stereotypical of their ethnic group!
