Seinfeld or Chris Rock sometimes include songs, though.

And if you're really a perfectionist, you could probably hear artifacting in the clapping. I have that on some tracks encoded at 64 kbps that I can hear inconsistencies in the clapping to comedians, so I don't doubt with a trained ear (not me) you might be able to hear it at 128. Not really a big though, as you're listening for the humor, not the musical content.
