A blonde and a redhead are walking down the street....

[NETim]

and as they walk by a floral shop, the redhead spots her boyfriend inside, buying her flowers.

OH NO!  She exclaims.

What's wrong? asks the blonde.

My boyfriend's in there buying me flowers. 

What's wrong with that?  Don't you like getting flowers?  asks the blonde, genuinely puzzled.

Well, I love flowers but he has certain expectations when he gives me flowers and I don't feel like spending the next 3 days flat on my back with my feet in the air, the redhead explains. 

Why, don't you have a vase?
