Blondes v Irishmen

Two Irishmen were standing at the base of a flagpole,  looking up. 
A blonde walks by and asked them what they were doing.

Paddy replied, 'We're supposed to be finding the bloody height of 
this flagpole, but we don't have a bloody ladder.'

The blonde took out an adjustable spanner from her bag, 
loosened a few bolts and laid the flagpole down. 

She got a tape measure out of her pocket, took a few 
measurements, and announced that it was 18 feet 6 inches. 

Then, she walked off. 

Mick said to Paddy, 'Isn't that just like a blonde! ........We need the bloody height

and she gives us the bloody length.'
