Whatso Funny? Does this joke make sense to you? Or should I say scents, which mean smells, or odors. The girl doesn't like the smell of the seats or benches. The boy points out that that is why the seats are called pews.When we smell something bad we can say P.U., even though this looks like and acronym, it isn't. I jst happens to sound like "pew" a name for a church bench.
