By the by,my friend Michael Vickers of Oxford has been working on Aristophanes
for several years now, and has written dazu: he believes Aristophanes is
*far* more obscene in his double-entendres than we have even guessed so
far. Guess what? He can't find a publisher for his work....The more things
change,....

I'd like to see some samples.

A number of sites include double entendres as a form of sexual harassment. So beware.
