Need a funny slogan/statement for girls holiday tshirts, any ide

Hi all

Me and my 2 friends (all girls) are going to Barcelona in 2 weeks on a girly holiday. We are looking for a funny slogan for tshirts we are getting made, any ideas?
Upto now I ahve thought of:

'Tell your boyfriend I said hi'
Blondes Tease, Brunettes Please'
'What would Barbi do'

Anybody have anymore?

Appreciated!

I can't deny it
I can be sweet sometimes

Do not touch what you cannot afford.... Obviously!

^^ I dont think you will understand it in the humour that I will, coz there is a tv ad in New Zealand where he says that, and its just hilarious, you have to see it for it to be funny. But I guess it could work on a girls shirt.
