I’m Pterrible

Behold, I present to you an absolutely delightful article of clothing that contains a humorous play on words. The source of amusement stems from the fact that the word 'pterodactyl' possesses the unconventional feature of being spelled using the letter 'p', thus culminating in a truly delightful pun. Isn't that exceedingly amusing? Explaining the joke helps, right?     S M L XL 2XL 3XL Width, in 17.99 20.00 22.01 24.02 25.98 27.99 Length, in 27.99 29.02 30.00 31.02 32.01 32.99 Sleeve length, in 8.90 9.17 9.45 9.72 10.00 10.39
