What's a good boastful/maniacal monologue?

-I will be auditioning for Beauty and the Beast (School Edition) and will be going out for the character of Gaston. I sing bass and have already found my audition song. Now all I need is a monologue. To fit the character, I was looking for a very self-absorbed, narcissistic, boastful monologue. This can be from either film, TV, or live performances. Thank you for your time.
