You've heard his voice in stuff like Toy Story and Rugrats, but Phil Proctor is probably best known for his work in the 1970s avant-garde comedy troupe The Firesign Theatre. My favorite album of theirs is the classic Don't Crush That Dwarf, Hand Me The Piliers, which he kindly autographed for me at an Audio Engineering Society event in 2012.

As you might notice, he also marked up the back—you can see that he wrote "AFTRA"—and I just had to ask why. It turns out that when they made the record, for some legal reason, the group of hippie comedians had to join the performers union American Federation of Television and Radio Artists (which is now part of SAG). So as a pun, they labeled the photos as "Before" and "AFTRA," but some bright spark in the art department thought it was a mistake and changed it to say "After" instead. So 40 years later, he reinstated the joke on my copy—how cool is that?
