Peanuts by Charles Schulz for January 17, 1964
Transcript:
Snoopy, Charlie Brown, and Linus stand together. Charlie Brown turns to Linus and asks, "Have you heard of a Diatryma?"<BR><BR> He continues, "He was a bird who stood seven feet tall and had a head as large as that of a horse! He had a huge sharp bill and poewrful legs with which he could run down small animals." Snoopy's ears fly up.<BR><BR> "He is now extinct...In fact, he hasn't been around for sixty billion years..." adds Charlie Brown.<BR><BR> Snoopy sits alone and thinks, "And we don't miss him a bit!"<BR><BR>
Probably a simple mistake substituting sixty billion for what should be sixty million.
