Last week the world mourned the loss of famed television producer, idol maker and eternal teenager Dick Clark, who suffered a massive heart attack and died at the age of 82.

Today, one of his contemporaries, Casey Kasem, turns 80 years old. The Lebanese vegan has logged more than 50 years of broadcasting history, beginning his career just as rock was emerging as the dominant youth sound.

The longtime host of syndicated radio countdown shows American Top 40 and America's Top 10 (plus a host of others) was also the voice of animated stoner hero Shaggy from Scooby-Doo. Kasem retired from radio in 2009, but he continued voice acting until late the next year.

Interestingly enough, he was also succeeded by Ryan Seacrest on the long-running Top 40 shows, just as the late Clark also passed the baton to Seacrest for New Year's Rockin' Eve. Is there anything that Seacrest can't, or won't, do?

His daughter Kerri Kasem is making a name for herself on radio, besides being a stunner, co-hosting Nikki Sixx's Sixx Sense broadcasts.

Of course, this whole blog is leading up to posting this clip of Kasem screaming and cursing in the recording booth. As someone who is familiar with recording his voice for broadcast, I can't explain why profanity seems to be the best medicine for a blown take.

Stand by for hilariously blue -- and ponderous -- language.
