Rush Limbaugh Is a Big Fat Idiot and Other Observations (ISBN 0-385-31474-4) is a 1996 American book by Al Franken.

It is satirically critical of 1990s right-wing political figures such as Pat Buchanan, Bob Dole, Phil Gramm, Newt Gingrich, and particularly radio host Rush Limbaugh.

Franken often makes his points through humor, including the use of graphs with his handwriting superimposed over them.

[3] Franken said his motivation for writing the book was the rise of Newt Gingrich, who used Limbaugh as "his mouthpiece".

[4] The audiobook version won the 1997 Grammy Award for Best Spoken Comedy Album.
