So funny I can't think of a proper title for the post to do it justice

This is from a message board for women who breastfeed. It is HILARIOUS. (It's also British, so for those who don't know, Tesco is a grocery store.)

Went to Abigail's school Christmas concert (no "proper" Nativity this year). Each class did a little something followed by a song or 2. Anyway, Ab's class did a Nativity scene, with Ab as Mary (How proud was I?). A few mins into their bit Ab promptly lifted her dress & shoved baby Jesus up it. The script then wandered away from what they'd learnt & goes as follows....

Joseph: "What are you doing?"
Mary: "I'm feeding our baby"
Shepherd: "Have you got a bottle up there then?"
Mary: "Don't be silly, he's having milk from my booby"
Joseph: "That's disgusting"
Mary: "No, that baby milk they have in Tesco's is disgusting. My baby's having proper milk"
Shepherd: "What's a booby?"
Mary: "Those sticky out bits ladies have"
Shepherd: "They're not boobies, they're nipples"
Mary: "No they're not, they're boobies"
Joseph: "So why can't Jesus have milk from a bottle then?"
Mary: "Because I haven't got a breast pump with me - you forgot to put it on the donkey"
Shepherd: "Can't you ask the teacher for a bottle to feed Jesus with?"
Mary: "No because this is the best way to feed Jesus. Anyway bottles haven't been invented yet & even if they were I've just had a baby so if you think I'm faffing about round Tesco's to buy baby milk when I make proper milk in my boobies you can think again"

I felt a teeny bit sorry for their class teacher - she did try her best to steer them back towards their proper lines but she was laughing so much she didn't really stand a chance. The line about Joseph forgetting the breast pump finished her off - she slid to the floor & couldn't get up for laughing....
