Why does every public toilet seat have a "Sit 'n Spin" feature?

Question

Are toilet seat nuts and bolts designed to be the weakest hardware known to mankind?

Answer 1

1) overuse

2) use by people who are heavier than its designed weight limit

3) abuse by vandals

Answer 2

How would you know?  You wouldn't actually SIT on a public toilet seat would you?

Oh yeah, 밑바닥 헌납자.  I forgot you men always have to out-p**p the guy in the next stall.  We women don't have that problem.  I can sympathize with you though.  At my previous apartment I had a seat like that.  Finally after months of sitting and spinning, I went to Wal-Mart and bought a new seat and installed it myself.  That was my "I am woman hear me roar" moment for the month.
