There are whole websites devoted to charting Bush's lies. Here's one of my favorites. plus a sample:
The Many Lies of George Dubya Bush
Today's Bush Lie
"[Castro] welcomes sex tourism," Bush told a room of law enforcement officials in Florida, according to the Los Angeles Times. "Here's how he bragged about the industry," Bush said. "This is his quote: 'Cuba has the cleanest and most educated prostitutes in the world.'"
"As it turns out, Bush had lifted that quotation not from an actual Castro speech but rather from a 2001 essay written by then Dartmouth University undergraduate Charles Trumbull. In the essay, Trumbull did appear to quote a Castro speech about prostitution. Sadly, the student made the quotation up.
"According to officials, the actual quotation from Castro's 1992 speech reads as follows: 'There are hookers, but prostitution is not allowed in our country. There are no women forced to sell themselves to a man, to a foreigner, to a tourist. Those who do so do it on their own, voluntarily. We can say that they are highly educated hookers and quite healthy, because we are the country with the lowest number of AIDS cases.'"
"...And this isn't the first time the Internet has baffled Bush. Back in 2003, the President cited another student's thesis when making a case to go to war. The student's [plagiarized and "sexed up"] work ended up in a government document describing Iraq's weapons capability. Not exactly the kind of hard intelligence needed to justify an attack on another country." The Register, 07.28.04
