A choir member once wore two different shoes by mistake to a performance. One was black and the other brown. It was quite noticeable during the whole service. The choir couldn't stop giggling about it after.
A choir member once fell asleep during a long rehearsal. When it was time for his part, he suddenly woke up and started singing the wrong song at first. Everyone was shocked and then burst into laughter.
In a small church choir, the choir director was trying to teach a new song. One of the older members, who was a bit hard of hearing, misheard the tempo instructions. So, when the choir started singing, he was either way too fast or way too slow compared to the others, creating a really comical effect.
I heard about a church where they were doing a play about the nativity scene. One of the donkeys in the play got loose and started running around the pews, chasing the shepherds. It was chaos but also really funny.
One funny story is about a choir that was supposed to sing a very solemn song. But one of the sopranos accidentally let out a really loud sneeze right in the middle of a long, quiet note. It completely changed the mood for a second and everyone had to hold back their laughter. Then there was a choir that had a member who liked to do funny dance moves while singing. At first, it was distracting, but then it became a sort of tradition in the choir, and they would all smile whenever he started his little 'dance routine'.
One funny church Christmas story is about the nativity play. A little boy was cast as Joseph, but he got so excited that he started ad - libbing lines. Instead of saying his scripted lines, he started talking about how he was going to take Mary and baby Jesus to the best pizza place in Bethlehem. Everyone in the church burst out laughing.
There was a time when a dog ran into the church during the offering and dropped a bone it was carrying right into the offering plate. Everyone was startled at first but then burst out laughing. It was a very unexpected addition to the offering that day.
Imagine a situation where a new pastor is trying to use the church's old and creaky pulpit for the first time. As he leans on it for emphasis during his sermon, the whole pulpit collapses. He ends up sitting on the floor in front of the congregation, looking a bit shocked at first but then starting to laugh himself. This kind of unexpected and clumsy moment can be very funny in a church setting.
A priest once accidentally tripped over the altar cloth while walking towards the pulpit. He managed to catch himself but not before making a very comical face. The whole church burst into laughter.
A methhead tried to wash his clothes in the dishwasher. He thought it was a great idea since it used water and soap. But all he got was a ruined dishwasher and clothes full of soap suds. He couldn't understand why it didn't work.
There was this one time when a young man got on the megabus with a huge backpack that was almost as big as him. He struggled to find a place to put it and ended up with it on his lap for half of the journey. Every time the bus jolted, he would be pushed forward by the backpack, which looked really comical.
