Conchy & co. appeared on a kids' TV show, The Mystic Knights of Tir Na Nog. In this case, though, Deirdre was his daughter, not his lady love.
Bwahaha! Conchobar makes a spooky appearance in the animated flick The King's Wake, which takes place on the Celtic holiday of Samhain (similar to our Halloween).
Conchobar didn't have a Round Table, but some scholars speculate that he might've been the inspiration for King Arthur. How's that for a legacy? (Source)
This king must've loved playing with pups. In Gaelic, his name means "lover of hounds." (Source)
