A Very Puzzled Blonde 
 

John gets a call from his very blonde girlfriend Buffy. 

"I've got a problem," says Buffy. 

"What's the matter?" asks John. 

"Well, I bought this jigsaw puzzle, but it's too hard.  None of the 
pieces fit together and I can't find any edges." 

"What's the picture of?" asks John. 

"It's of a big rooster," replies Buffy. 

"All right," says John.  "I'll come over and have a look." 

So he goes over to Buffy's house and she greets him by saying, "Thanks 
for coming over."  Buffy leads John into her kitchen 
and shows him the 
jigsaw puzzle on the kitchen table. 

John looks at the puzzle and then turns to her and says, "For heaven's 
sake, Buffy, put the cornflakes back in the box." 

I guess she didn't have all her flakes in one box.
