Have you noticed twenty begins with a "t" So twenty suits me to a t.

There's nothing wrong with a 20 ton truck
or twenty trees on a truck
to brew a nice tea you need 20 tea leaves in a tea-pot.
There could be 20 task that need to be done.
It might even take 20 toes to tango
There are many ways to tie 20 to a "t"
