An American grammar question (totally off topic)

[Chavster]

Lets say, just as an example, Barack Obama and George Dubya Bush meet up one night and they go to the Olive Garden for some spaghetti with three cheese marinara, salad, and breadsticks.

The next morning, news headlines (newspapers and online) might look like this:

OBAMA, BUSH EAT SPAGHETTI AT OLIVE GARDEN

Whats with the comma? Any time I read an American newspaper or website, and they're talking about two or more things/people, they never say:

OBAMA AND BUSH EAT SPAGHETTI, or BUSH & OBAMA EAT SPAGHETTI.... its always BUSH, OBAMA EAT SPAGHETTI

Who taught you people that? Its awful!  

(I do realise there are more important issues in the world. I'm just killing time before dinner)

It's just something we do to piss off the Brits.   

[Chavster]

It works!

[tomgallagher]

Probably the same guy that taught you Brits to begin every other sentence with "right".

[Chavster]

Do we?

For example, 'right its really warm today'?

[tomgallagher]

Y'all sure do get your money's worth out of that little old word.

[Chavster]

I've never noticed. Its not a way I begin my own sentences. Can you give me an example? A real one that is

[tomgallagher]

Right. just listen to the BBC shows.

[Razor X]

Can't say I've ever noticed with the possible exception of certain charcters on EastEnders.

OK, here's my take:  If it's in a newspaper it's simply a method they use for a terse headline.  Nothing more.  Anyone else agree, disagree?

Red

Agree.

[tomgallagher]

Agreed.

[Chavster]

I dont know what that means

[Sly Red]

Terse as in short and concise.  You've just spoiled my perception that Brits have better vocabularies than Americans. 

I'm shattered!

[Chavster]

I know what terse means, you young whippersnapper you but I was trying to think of 'terse' in conjuction with my spaghetti analogy

I dont think it matters whether the headline is suppose to be terse or not...its just that comma thing, it seems to be used all the time, and I just dont get it
