Oh, it's getting harder and harder!
No, not that! What straws should you get. First we had multi Coloured, then we had flesh, then came the glowing (which i preferred until now) .... now we have got black.
Well they say that variety is the spice of life .. so why not grab a pack of each and then have time slots for each type of straw. Say between 7 and 9 all the girls have to drink through their multi coloured straw. 9 till 10 you all swap to the flesh, 10 till 11 only sucking through the glow and from 11 till when ever you can only sip from the black.
Penalties (remove an item of clothing - kiss the ugly bloke at the bar - buy a round of drinks) to paid by anyone caught drinking from the wrong straw.
Each pack contains ten black straws (willy shaped of course!)
