S is for Serta...Sheep
Seriously. They crack me up. Every time. I even have a good collection of them at home. I don't know why I find them so funny, but I do. They remind me a little of Wallace & Gromit, too. But, really, it's just because they're funny looking. And they're sheep. And, I'm sorry, but sheep (at least fake sheep) are hilarious.
I don't really have a lot to say about Serta...I don't own a bed by them and I'm not sure I will (I think the Sleep Number is more my style). But, their advertising campaign will probably always stick with me.
