Irony, sarcasm, or coincidence?

Listening to CNN Headline News on XM Radio a couple of days ago, I found this juxtaposition of news story and commercial to be smirk-worthy. The story concerned the polygamous uproar going on in El Dorado, Texas, and the collection of DNA from all concerned so family groups could be matched up. The commentator broke for a commercial, a commercial for an erectile dysfunction drug.

Irony, sarcasm, or coincidence? You be the judge.
