Well here's mine:

#!/usr/bin/env ruby
require 'date'
month = ARGV[0] ? ARGV[0].to_i : Date.today.mon
year = ARGV[1] ? ARGV[1].to_i :  Date.today.year

month_names = %w{January February March April May June July August September
                 October November Decemeber}

dow_banner = %{Su Mo Tu We Th Fr Sa}
days_in_mon = Date.civil(year, month, -1).day

# Print title:
print " " * ((dow_banner.length - 
            (year.to_s.length + 1 + month_names[month - 1].length)) / 2)
print "#{month_names[month - 1]} #{year}\n"
print "#{dow_banner}\n"

dow_counter = Date.civil(year, month, 1).wday

print " " * 3 * dow_counter

(1..days_in_mon).each { |i|
        if i < 10
                print " #{i}"
        else
                print "#{i}"
        end
        print " "
        dow_counter += 1
        if dow_counter % 7 == 0
                print "\n"
        end
}
print "\n"
