SEO for a podcast - How?

I'm doing a bit of a donation of some SEO to my favourite podcast, and just wondering if anyone knows any tricks or methods.

I can rank their site about the podcast just fine but I wouldn't mind giving them a push in Itunes as well if thats possible.

The podcast is "Sick and Wrong"
if anyone's interested, it's been giving me an hour and a half of warped entertainment for 5 years, so I just wouldn't mind giving them a bit back.

If anyone out there is a listener already and you feel like helping Dee & Lance, the keywords I'm going after are "howard stern podcast" and "comedy podcast". If you want to help then do a blast to that website with those keywords.

C'mon - someone must know something!!! This is the SEO equivalent of Pro Bono work

Build them some high PR backlinks, that's really your best bet since you don't control their page.
