Among my favorite podcasts are the NewsHour with Jim Lehrer, the Slate Daily Podcast, and the Onion Radio News.
Fairly recently the Onion ran a story about a retired marathon runner which I found very funny and would like to share with you. If you are not familiar with The Onion it is a tongue-in-cheek satire news source.
You should be able to hear the podcast by clicking here. If you have trouble with this link you can also find the podcast here.
UPDATE (10/5/06): I should note that the podcast is all of :30 in length.
