Changing slogans/quotes

Thinking along the lines of recreating quotes/slogans, I've just had a play around with Photoshop, I found 3 slogans that I have had a go at changing slightly:

This was really fun changing some well known companies slogans and flipping it giving them the totally opposite outcome to the customer. 
When im in uni ill have a go at printing these off at A1 size (as if they were bulletins) and see what they would look like at a large scale. 
This would be even more interesting if I could produce an advert like they show on TV but using the new slogans .....
