jokes and jokes and jokes

ok just one joke, but first a simple laugh:

so a dyslexic guy walks into a bra...

now for the joke:

Jewish man walks into a bar, sees a Chinese man.
J: "I never forgave you Vietnamese for Pearl Harbor."
C: "I'm Chinese, and that was Japan."
J: "China, Vietnam, Japan, what's the difference?"
C: "I never forgave you Jews for sinking the Titanic."
J: "That was an iceberg."
C: "Goldberg, Greenburg, iceberg, what's the difference?"

Side note:
Why does spell check suggest I capitalize China and Vietnam but not Japan? Very odd.
