Rick and Morty is a fantastic show!  The writers Justin Roiland and Dan Harmon are brilliant.
I don't think I have ever seen it.  What is it about?
It follows the misadventures of Rick Sanchez, a mad scientist, and his grandson Morty Smith.  They go on a variety of adventures, including interdimensional ones!
Interdimensional, huh?  I take it that it is a cartoon?
Yes, it's an American adult animated science-fiction sitcom.
Ahh.  I may have to check it out then.  I like cartoon's, from time to time.
It's on Adult Swim, which is Cartoon Network's late-night programming.  You should check it out!
