'The Weekly Planet' is the only one I listen to regularly. Couple of blokes from Melbourne, Aus talking about pop culture, but I'm mostly there for the funny banter and obscure Australian references.

I binged on Tony Martin's 'Sizzletown' a while back. It's a 'late night talk-back podcast' - basically Tony doing a bunch of characters that 'call in' to the show. Pretty funny, especially the first couple of seasons.
