If you appreciate this style of ad delivery (and don't mind his...uh....language), comedian Bill Burr's Monday Morning Podcast and Thursday Just Before Friday Monday Morning Podcast has some hilarious ad reads. He hates doing it, he hates having to do it, and he openly mocks how silly some of the ad copy can be.
Which apparently is fine by his sponsors because apparently they convert incredibly well (it might also have to do with Andrew Themeles, producer and comic as well allegedly is very particular about who they are willing to be sponsored by since neither of them are hurting for the money).
But I agree, ads that are just naturally read and we get back to the show is preferred. The minute someone tries to get 'disruptive' with ads in podcasts I fear the whole house will come crashing down.
