I had a routine dental checkup just now.
I was hoping for zero cavities. I was really happy when the
dentist announced zero cavities after observing and probing my
teeth.
Unfortunately, after the scaling process..... whoops, one cavity
was uncovered, and it had to be filled before it got worse.
My bill shot up as a result. 
Now I'm worried. I hv not been to the dentist in 10 years coz
I'm lazy -_-"
