For 11 and up?! Come on common sense! What are you thinking?! There are sex jokes, and language! But this is VERY hilarious. The "sex jokes" are this. A lot of reference to groins, president Skroob is shown in bed with the two twins. Not only that, but UNDER the covers, and you can hear them giggling. Near the end, Lone Star, and Barf, go to a dinner. When the waitress asks what they want, Barf says cleavage by accident. For the waitress was wearing a Revealing top. Barf's tail also goes up behind the waitress's skirt. But this is all funny. Funny for older people.
As for the language, just you're regular. The B word, s word, and even one f word. Ok, so that one word is not the regular.
Thanks for reading this monotonous, queer review. And I hope it helped you decide!
