Subject: passing a method

I want to make a method which can execute another method given to it as
an argument. The following works but the call doesn't look elegant - is
it the ruby way?

wybo>cat test.rb
#!/usr/bin/env ruby
@t = ''
def bye
  @t << 'bye'
end
def hello
  @t << 'hello'
end
def doit(f)
  f.call
end
doit(method(:hello))
doit(method(:bye))
doit(method(:hello))
puts @t
wybo>ruby test.rb
hellobyehello
wybo>
