What rhymes with 3????

I am the type of person who is all about wording. I got writer's block while helping my sister with her daughter's birthday invites. Needed something that rhymed with the number 3, hmmmmm??? I googled and found a really great web tool. It is called http://www.rhymer.com/. I am always using a thesaurus or dictionary, and now I am very happy to be able to refer to this site for my rhyming word needs!
