Well, it depends on what message you want on it. Some department stores have good funny ones, and cooking specialty stores usually have a good variety. I think we could help you more if you specified what kind of funny saying you want on it. CookinBlondie*
I have seen one of those, but I don't know if you have one of these stores near where you live. But, kiss the cook aprons are pretty common. I'd say you might find them at JC Penny, maybe even target. I know that either Sears or JC Penny has some with Emril on them. The place I am thinking of is called Wilderness Outdoors. Do you have any cooking stores near where you live? I would try one of those.
