A couple of buddies of mine from econ grad school at UT, Jason DeBacker and Rick Evans, have a very successful blog with good insight and a running compilation of the best econ jokes available. their blog was recently cited as an officially sanctioned AEA blog, and perhaps more importantly referenced by Mankiw's blog (see ad hominem post).
btw, if you check out Rick's professor page
he has a link to UT econ intramural sports recaps.

rick to me to Debacker for a TD!)
