Shocked! I say, SHOCKED!! Literally vibrating with disappointment! Blue-faced horror! WHAT, indeed, is this WORLD COMING TO? I ask you... Eheuh! <clutches pearls>
Oh, here's one I forgot -- the greatest newspaper headline of all time, after Inverness Caledonian Thistle (known as Caley) upset Celtic in the Scottish Cup:
I don't think Mark Twainkie is a proper pun. But come on Paul, take another trip through Buffy the Vampire slayer and tell me you don't love a good pun!
The problem was that the poll's only alternative to embracing puns was to condemn them utterly and universally as never acceptable. I suspect a less extreme choice would have likely produced much different results.
Also, Google provides a link to an exhaustive list of pun-based porn titles. I didn't get very far down the list, but most aren't very good (though "Ocean's Eleven Inches" isn't horrible).
You wouldn't have made it into the Vancouver SF pun contest qualifying rounds.
SUPER CALEY GO BALLISTIC, CELTIC ARE ATROCIOUS
Q: why do ghouls hang around with demons?
