Are you a comic sans criminal? I stumbled across this website and I really like it. Not only does it play on the fact the most serious graphic designers and typographers hate comic sans with a passion, but it actually gives some information as well. It says why it was originally designed, when it has been used inappropriately and when are the only reasons to use this font, one being that dyslexics find it easier to read (although it explains that there are far better fonts to be used than comic sans for these reasons).
This website is great to look at as well, I love the colour scheme and think that it merges well with the type and layout used. It's a good thing the type works as it is slagging off another font, so to mess up your own typography would be awful and quite contradictory.
It also has helpful links to crack that comic sans habit. These include:
