Subject: "puts, if and unless" VS "nil"

Rubysters,

I was sharing with some friends how to use if and unless. I wrote this
statement: *puts nil if nil*
and I got =>nil. (Which implies nothing was printed.)

When I wrote: *puts nil unless nil*
I got:
nil
=> nil
Which implies that puts output nil.

My question is what is in *"nil"* that makes "*puts*" print "*nil"*? Or is
there any explanation to back this behaviour?
