Little (72x4) code snippets that were sufficiently eye-catching would be
a nice positive way to do it. Not along the lines of perl's JAPHs, more
like code whose meaning is obvious when you read it, and which is cool
in a "wow - Ruby lets you do it that simply/elegantly/enjoyably?!" sense.
(The Haskell quicksort is a perfect example of the sort of thing I have
in mind). 

Some off-the-top-of-my-head examples (and I'm sure there are several far
better ones)

def twice; yield; yield; end
twice {print "Hello World"}

nthreads.times {|i| Thread.new {task[i].call}.join}
#Multithreading Ruby style. 

"hello world".gsub(/\w*/) {|match| match.reverse} # => "olleh dlrow"

print "hello #{name}" if friends.include?(name) unless no_greet

a, b = b, a # who needs temp variables
