Oh no, Paul, please don't stop making "puns" - now that I've just learned the word! I love them - at least when they're so thoroughly explained when I don't get them at all ...
(For the other members who try to manage with English as a foreign language: "A pun, or paronomasia, is a form of word play that deliberately exploits an ambiguity between similar-sounding words for humorous or rhetorical effect Such ambiguity may arise from the intentional misuse of homophonical, homographical, homonymic, polysemic, metonymic, or metaphorical language." )
I know "Perry Mason" is a well known attorney character and surely some of the movies have been shown in our tv too but I've missed them so Della Street - never heard of... (now I know 3 streets in your country)
