This is something that's been bugging for a long time.

Lots of times on TV, there's a person in the shower, someone comes and
flushes the toilet and the person in the shower starts screaming and
freaking out.

Why does the person in the shower react that way?

Because the flushed toilet is taking all the cold water while
refilling its tank, scalding the person in the shower.
