There are some hilarious verses in the Qur'an. For instance, the Qur'an claims that the sun sets in a muddy pool (18:86), that semen is formed between the backbone and ribs (86:6-7), that the earth is flat (88:20), that there are seven earths (65:12), that the sun orbits the earth (36:38-40), that human embryos are blood-clots (22:5), that the sky will fall on the earth if Allah doesn't hold it up (22:65), and that stars are missiles that Allah uses to shoot demons who try to sneak into heaven (37:6-10; 67:5).
But for some reason, the funniest verse in the Qur'an (in my opinion) is Surah 33, verse 53. The verse reads:
O Ye who believe! Enter not the dwellings of the Prophet for a meal without waiting for the proper time, unless permission be granted you. But if ye are invited, enter, and, when your meal is ended, then disperse. Linger not for conversation. Lo! that would cause annoyance to the Prophet, and he would be shy of (asking) you (to go); but Allah is not shy of the truth. And when ye ask of them (the wives of the Prophet) anything, ask it of them from behind a curtain. That is purer for your hearts and for their hearts. And it is not for you to cause annoyance to the messenger of Allah, nor that ye should ever marry his wives after him. Lo! that in Allah's sight would be an enormity.
Notice that Muhammad, who tells his followers it's okay to beat their wives (4:34) and to rape their captives (4:24), is nevertheless so incredibly shy, that he can't bear telling his followers that they're annoying him by hanging out at his house and talking his ears off. But Allah isn't shy, so Muhammad (the shy one) delivers a revelation from Allah (who's not shy) telling Muslims not to annoy Muhammad by showing up at his house early or staying late for conversation.
The Qur'an is supposedly Allah's eternal Word. Yet many verses of the Qur'an have no purpose other than satisfying Muhammad's desires. How much more obvious could it be that the Qur'an is not the Word of God?
