Mr. Creosote, even if I want to look away at parts!

How did I know that one would come up first?

The Miracle of Birth with the door-opening sequence and "the machine that goes 'ping!':"

Obstetrician 2: And get the machine that goes 'ping!'.
Obstetrician 1: And get the most expensive machine - in case the Administrator comes.
Hospital Administrator: Ah, I see you have the machine that goes 'ping!'. This is my favourite. You see, we lease this back from the company we sold it to - that way it comes under the monthly current budget and not the capital account.
[The doctors and onlookers applaud.]
Hospital Administrator: Thank you, thank you. We try to do our best. Well, do carry on.

Catholics vs Protestants with the whole Every Sperm is Sacred song and the conversation between Mr and Mrs Blackitt:

Mr Blackitt: When Martin Luther nailed his protest up to the church door in 1517, he may not have realised the full significance of what he was doing, but four hundred years later, thanks to him, my dear, I can wear whatever I want on my John Thomas. And Protestantism doesn't stop at the simple condom. Oh, no! I can wear French Ticklers if I want.
Mrs Blackitt: You what?
Mr Blackitt: French Ticklers, Black Mambos, Crocodile Ribs... Sheaths that are designed not only to protect but also to enhance the stimulation of sexual congress.
Mrs Blackitt: Have you got one?
Mr Blackitt: Well, no... But I can go down the road any time I want and walk into Harry's and hold my head up high, and say in a loud steady voice: 'Harry I want you to sell me a condom. In fact, today I think I'll have a French Tickler, for I am a Protestant.'
Mrs Blackitt: Well, why don't you?
Mr Blackitt: But they! They cannot. Because their Church never made the great leap out of the Middle Ages, and the domination of alien episcopal supremacy.
Narrator: But despite the efforts of Protestants to promote the idea of sex for pleasure, children continue to multiply everywhere.

Mine is hands down (pun definitely intended) the guy with the long arms. So thoroughly bizarre, even by Python standards!

Everyday in heaven is like Christmas.

'Every Sperm is Sacred' song.

My favorite part was watching it with a devout Baptist. His comments warmed the cockles of my heart.

"I find this offensive. I mean, what they are saying is true, but it is still offensive."

The Crimson Permanent Assurance

15 minutes of perfect Terry Gilliam nonsense.

No, I believe that skit was featured in And Now For Something Completely Different. If not, then it was definitely in the television show.

That is correct. The one @mechajutaro asked about is from the sketch movie "And Now for Something Completely Different (1971)". The original version was in the episode "Monty Python's Flying Circus: The Naked Ant (S1E12, 4 Jan 1970)". It was remade - with the omission of some scenes - for the above mentioned movie. There are some differences between the two versions.
