Let's make this clear: although I like Jack Black, I do get tired of him playing the same damn character over and over. That's why the comedy tracks on this album are funny but will get old.
It's the sad fate of most, if not all, comedy albums. Jokes get state once you've heard them enough. When I first heard "Drive-Thru", it was freakin' hilarious! Now that I've heard it a bunch of time ... not so hilarious. A chuckle, but that's it.
But don't let that stop you from buying this album. The music is fantastic! The songs manage to both mock and celebrate the folk-rock of the early 70's, and the production is high quality. Vocals and guitars jump out at you and shake you around like a hug from a big uncle who's been drinking too much. This is not a comedy album with a few chords strung together to provide a backdrop for a few gags. The music is truly well written, played, and produced.
Just be careful: the songs do get a tad vulgar at times. Okay, they're extremely offensive, but that's what makes them great. If you're an uptight person who managed to ignore the two naked fat guys standing before a great horned Satan on the album's cover, then you're in for some trouble. This is not for your mom's ears.
