We usually don't post about stuff like this, but the other day our son told us that he saw Two-Gun Bob turn up in an episode of Scooby-Doo — well, it wasn't Two-Gun Bob exactly, but...
The episode, "The Shrieking Terror," is part of a new cartoon series titled Scooby-Doo! Mystery Incorporated. The Scooby-Doo gang goes off to college where they meet Harlan Ellison (who actually provides his own voice for the show).
In the show, Harlan is confronted at a lecture by a Robert E. Howard stand-in named "Howard E. Robertson" (there's also a writer named H. P. Hatecraft in the show — do you detect a theme?).
Before long a Lovecraftian beastie starts to terrorize Ellison and the campus.
Once foiled and unmasked, the monster turns out to be none other than "Howard E. Robertson".
...and he would have gotten away with it, too, if it weren't for those meddling kids!
UPDATE: In our comments section, Rick Tucker is absolutely right. Don't watch this cartoon thinking that these characters actually portray REH or HPL. Despite looking a bit like REH (Hatecraft doesn't really look much like HPL), the Howard E. Robertson character is shown as a fannish dolt out to get revenge on anyone who doesn't share his devotion to Hatecraft. And yeah, It's irritating to see the Howard stand-in portrayed this way. Hopefully Scooby-Doo cartoons aren't most people's source of biographical information — but you know they probably are.
