Subject: stepping through arrays simultaneously

Suppose I have two arrays, one holding times, and the other holding 
events corresponding to the times.  I want to step through both arrays 
at the same time.  Is there an elegant way to do this?  For example:

times = [ '1', '2', '3', '4', '5']
events = [ 'eat', 'sleep', 'eat', 'play', 'sleep' ]

times.size.times { |cnt|
   puts times[cnt] + ": " + events[cnt]
}

That's not too pretty; at least, I think the times.size.times {block} 
is ugly.  Is there a way to join the arrays into an array of n-tuples 
and step through them one tuple at a time?  I'm a newby, and not 
entirely sure what ruby builtins would make sense for this.  Thanks!
