Where do you find good novelty/cartoon ties?

I have a few Looney Tunes ties I got from my dad several years back as well as a couple other humorous offering (Pink Panther, Winnie the Pooh). I wanted to get a few more ties like this as people generally like them, I like being a bit more dynamic, and they're a good ice breaker when I'm teaching a class (nothing blatantly unprofessional). For the life of me though, I can't find any places that sell them. I've come across some on-line vendors, but I have no idea about their reputation.



The best I've bene able to do is find "Museum Artifacts" series ties at a local retailer (presidents, Van Gogh, math formulas). Do you all have recommendations on where I might look or any decent on-line vendors for ties?



Thanks,
