"Hello to Jason Isaacs." This meme initially comes from Mark Kermode's (and Simon Mayo's) habit of... saying hello to Jason Isaacs (a former classmate of Kermode's) on their film reviews show. Now this meme hasn't spread a lot on the Internet, but it seems to be appearing in increasingly bizarre situations in real life. See for instance:
Someone saying hello to Isaacs in their marriage speech.
Someone else, having met Kermode in a hospital, actually saying hello on the tannoy.
A writer at the Tonight Show with Jay Leno is apparently a fan of Kermode's show and has been including the sentence in a few◊ graphics◊.
Said writer sent an e-mail to Kermode and Mayo and can be heard here (with the images included).
Then an engineer working for Google (UK) joined in. So as of February 10th, 2012, when you type "Jason Isaacs" on google.co.uk, this◊ is what comes up.
The words "Hello to Jason Isaacs" have been uttered on Swedish radio.
Title Drop at the end of Paul Harvey's The Rest of the Story, a radio show in which the host would share a story of someone or something fascinating, denying one key detail until The Reveal at the end. The phrase is often used in Real Life whenever one shares a long story with someone else.
