For those that have been living under a rock for the last 40-years, or that lack the cognitive ability to connect a few simple dots, I shall explain . . .
The Bachelor Chow is a reference to a Fox TV show called Futurama. It's a "product" that's available in the future for unmarried men (aka as bachelors) and the main character in the show, Frye, actually eats it.
The reference to shipping (sex) dolls and androids/robots to China is a tad more complicated, but still comprehensible to anyone with an IQ that's approaching 3 digits.
First, China has had a "one child per family" policy for a number of decades now. And virtually every family wants a boy, not a girl (sounds sexist to me but you'll have to take that up with long-standing Chinese culture, Mao and his successors, not me). Due to that fact there are apparently a lot more males that females "of age" in China these days.

Consequently with proportionately fewer females around a lot of those men are feeling a need for "companionship". So it seems that dolls and androids/robots to fill that need are becoming more popular. Someone over on that side of the pond even tried to start a "rental" service until they ran afoul of Beijing. Again, take it up with Mao and his successors if you have a problem with that, not with me.

As to the Jewish American Princess jokes (the same ones can be told about Redneck American Princesses, or WASP American Primnesses, or whatever) . . . I got those a LONG time ago from a now dearly departed friend that frequently wore a yarmulke for some reason. (He was Jewish in case you're a bit slow to catch on . . . ) He also referred to the Olds 98 station wagon that his parents had when he was a child as a "Yom Kippur Clipper". One of his favorite jokes for some reason (aside from the "Debbie Does Dishes" one) was that every Jewish woman's perfect dream home involved 6,000-square-feet of floor space, but had no kitchen and no bedroom. He though it was all very funny, nothing serious about it. After all, if you can't poke fun at yourself who can you poke fun at? And I always believed that too until I saw your nasty response so maybe those jokes aren't very far off the mark after all, assuming that it wasn't the bachelor chow or the sex dolls that set you off. Or maybe they just hit a little too close to home for you?
Anyhow, I don't find those jokes to be nearly as offensive as some of the very nasty remarks made on this very WEB site regarding those of us with a conservative bend. But to each their own I suppose.
