After more than a year I continue the successful series of alternative fonts of classics. A generally hated typeface is Comic Sans, mostly because of it's misuse. There are even hate/love blogs about this font (http://bancomicsans.com/) and they try to raise money for a documentary. The font was designed Vincent Connare in 1995 and most designers wouldn't touch the font in a professional work, but with sometimes we need something similar.
Top Alternatives
Comic Jens Not only is Comic Jens from Jens Kutilek a high quality opentype font, with ligatures, context sensitive letters and symbols, but it's also free. (www.kutilek.de/download/comic-jens.zip)
Joker Joker is a typeface designed by Jerry Inscoe and it's based on his handwriting. A great font with alternative letters and additional letterforms (www.handselecta.com)
