Spam random Chuck Norris facts to a list of target e-mails (spammy April Fools joke)

chuckify.sh

#!/bin/bash

# Generate a random Chuck Norris fact and e-mail it to the target
# Requires the 'cowsay' and 'cn' (https://www.npmjs.com/package/cn) programs to be installed
# Requires Mailgun API key
#
# Usage: ./chuckify.sh NUM EMAIL
# ...where NUM is an integer of how many e-mails to send and EMAIL is the target's e-mail
#
# Replace placeholders (Mailgun API key and domain)
