Derry Murbles is the host of Thoughts for Your Thoughts on WVYS Wamapoke County Public Radio. He is bald, bespectacled, and has a very subdued demeanor.
Derry is first seen filling in for David Parker, who left to study the migration patterns of the nation's squirrels and hasn't been seen since. Derry eventually became the full-time host (later co-host) of Thoughts for Your Thoughts.
Derry is played by Dan Castellaneta.
Season 5 Edit
In Pawnee Commons, Leslie appears on Thoughts for Your Thoughts to attract park design submissions for Lot 48.
In Anniversaries, Leslie returns to Thoughts for Your Thoughts, which is now co-hosted by Derry and his Eagletonian co-host August Clementine. The two men have an antagonistic relationship. August provokes as violent a reaction in Derry as Derry seems capable of having.
