Dennis pulls down his pants in front of guards. No frontal nudity seen, his butt seen

A boy's penis is seen as he is about to urinate.

A woman temporarily appears without any clothes on. (This applies to the PG-rated DVD version of the film.) A nipple is shown briefly (about a second). She is shown walking toward the camera completely nude (full-frontal - head to toe). While in shadow, most features are still visible. There are also several shots of the side of her breast.

Several people are attacked by the Jabberwocky. You do not see the attack, but the beast drops their remains into camera view. The bones are bloody and have been stripped of their flesh, leaving only the head intact.

A man has cut his own foot off. During an extended scene, you are offered multiple views of the bloody stump with the foot lying next to it, along with the knife. The man is not in noticeable pain, and views this as a smart move for a beggar.

A man is decapitated off screen. Later, his head is seen lying on the ground, which is then kicked off screen and later tossed away when someone realizes they are holding it.

Many knights are killed in a jousting tournament, mostly off screen.

During the jousting tournament, the spectators are progressively covered in more and more blood, splashing onto them from the knights.

A knight in armour is cut in two down the middle, with some blood splashing up.

All of the above is very comedic.

The "F" word is heard once out loud, and another time obviously mouthed (though unvoiced or edited out) by the squire talking to Michael Palin's character about the night vigil.

In a bar, all of the patrons are drinking.
