What do Jerry Seinfeld and Steve Jobs have in common?

Simple question. Take your time.

Both Jews?

The same initials, though in a different order?

Lots of money?

I couldn’t care less about either of them?

Neither of them ever murdered a prostitute - that we know of?

Good observations, but no so far. It’s something that people would not expect. It’s not behavioral, it’s not a hobby, and it’s not lifestyle related (like being rich).

Both have managed to avoid Lou Gerhig’s Disease.

Both Seinfeld and Jobs have all their limbs. No amputations there.

Jerry is the bizarro world Steve.

They like the same TV show?

It’s the size 8E shoe - isn’t it?

They both like the Mets.

Neither one has been in my kitchen!

Good Twix, now how much did you wager?

Its Elaine: They’re both driving hard to the Hoop.

Neither of them has ever been in my kitchen?

Both of them are really animatronic robots from the future?

Damn, another Cliff Claven idolator!

Well astro despite your second posting (it’s not a lifestyle or a hobby), I believe they are both Porsche fanatics.
(That probably qualifies as a lifestyle and hobby but I just thought I’d take a guess).
