how come the if statement returns true? in ruby booleans part 4.

how come the following if-statement returns true? I don't see it defined anywhere, and yet it works. I would get it if we first would put something like "todo_list.remove_item("eggs")", but we don't, and I would guess the default setting is false, so how does this work? 

if todo_list.remove_item("eggs")
  puts "Eggs were removed from the list."
end

remove_items is defined and returns true or false depending on whether that item was in the list, see code under this video:
