This is OT, but I'll post this just to give perspective on the "funny" matter.
I once knew a teacher (she used to be a math teacher in our school) who went to Africa to teach at some remote African village. Her house was near the school, and there was no interior bathroom, just an outhouse, and a dirty kitchen, where she brushes her teeth every morning. Now, everytime she brushes her teeth, it was a spectacle to the local children and some of her pupils who live nearby, because each time she brushes her teeth, in full view of the children, the children would then giggle and laugh each time she gargled water and spat it out into the sink. The older children even shook their heads in disbelief. She just smiled at them whenever this happened. But one day, she couldn't stand it anymore and had to ask one of the villagers at why the children found her daily brushing ritual fascinating.
She first asked if the villagers used toothbrushes, and the villager said yes, they used toothbrushes, confusing the teacher further. The villager then said, "They are perhaps curious, amused, puzzled, because you spit out the water into the sink..." but she didn't elaborate and walked off. The teacher became all the more puzzled, and was so keen on getting to the bottom of the matter, that she visited one of the local village communal baths, to see how the villagers brushed their teeth. And this is what she saw...
One of the villagers, while brushing his teeth, spat the water out into a basin, where another villager was washing her feet. Water is so precious a commodity (they haul it out bucket by bucket, barrel by barrel, from a reservoir halfway to the next village), that they "share" their water this way.
So, our own way of doing things may indeed look funny or curious to another peoples' culture.
