A brunette, a redhead and a blonde go into a bar.

The brunette tells the bartender she would like a M L. The bartender puzzles about the request and finally asks, "What is an M L? The brunette replies, "A Miller Lite duh"!

The redhead tells the bartender she would like a B L. The bartender puzzles about the request and answers,"You want a Bud Lite"! The redhead looks at him and says, "duh".

The blonde tells the bartender she would like a 15. The bartender puzzles about the request and just can't figure it out and asks the blonde what a 15 is. The blonde replies, "A seven & seven duh"!

"A seven & seven duh"!

I don't get it - must be a "regional" (USA) joke.

I am assuming one of the 7's refers to 7-UP but what is the other 7?

I had heard of the drink but was in the same boat as you, MG.

Wiki tells me this
so now we both know! Cheers...

Glad I wasn't alone in not getting it !

Commonly known as a rye and seven.

Rum and Coke is nothing like it except for the number of words in the name. It is more like Ginger Ale with a kick. (Or at least that's what I'm told. Don't touch the stuff myse-hic-lf.)

No, rye and seven is rye and seven-up. Rum and coke and ginger ale with a kick are completely different.

You didn't make the Rum and Coke remark, I made my input to the Wiki quote made by ozzz2002. Rye and seven and ginger ale with a shot of whiskey couldn't be any closer to each other.

I love bar jokes. Here are two of my favourites:

Q. What did the bartender say when a horse walked into the bar?

A. Why the long face?

I won't include the second because it will probably get edited out.

Charles Dickens walked into a bar and ordered a martini. Barman asked 'olive or twist?'
