The thing to keep in mind about Firesign Theatre is that, even though they're a comedy troupe, they're not really "funny." What they are, however, is brilliantly surreal, absurdist, and stream-of-consciousness.  You have to let this album wash over you.  Perhaps several times.  There are no "jokes," per se, but there are moments of genius lunacy.  The album is about an old actor watching his films on TV.  He changes the channel several times and you get to hear snippets of commercials and other shows.  "Welcome to the world of snails and adventure." is one of my favorites.  Another is near the end of the album when someone says, "MY, MY..."  Even my kids like this album.
