You can even listen to a clip of LBJ and his pants:

Johnson was well known for his coarse language and occasionally unrefined behavior. While not a gaffe in office, an embarrassingly personal tape of LBJ ordering pants from Joe Haggar on August 9, 1964, was later released to the public. In it Johnson belches, complains about the pants riding up and cutting him “where your nuts hang” when he gains a little weight, like “riding a wire fence,” and asks for more material “around under my bunghole” that he can let out if need be.

And I would have thought there would be more entries for W, but then again, his term isn’t finished yet.
