Here's something you can do to find out more about a method:

irb(main):006:0> method(:gets)
=> #<Method: Object(Kernel)#gets>
irb(main):007:0> method(:gets).owner
=> Kernel

Then you can do "ri Kernel#gets" and get the docs (or look online at
http://www.ruby-doc.org/ of course).

Well, but then you could not have all these nice little chats with us. ;-)
