Doing a last-ditch effort to make it to Santa's naughty list, Zac Efron's sweetheart of a mother Starla Baskett gave the "Dirty Grandpa" star a penis pasta cookbook for Christmas. Efron posted a photo of his outrageously cheeky present on his Instagram account.

 "You know your mom's on point when she puts this in your stocking," the 28-year-old hunk captioned the snap of the gift, which showed off a perfectly garnished bowl of penis-shaped pastas situated just below the equally eye-catching title.

According to E! Online, a novelty item such as Efron's unique and unexpected Christmas treat is mostly found in sex shops although the site noted that Amazon and eBay also has the recipe book for the taking. Either way, Mama Efron must be chuckling wildly the minute she purchased it as she thought of Efron's reaction.

On Amazon, the cook book appears to be a huge hit, with buyers almost always rating it with five stars. Majority of the people that bought the book had the same reason as Efron's mother in deciding to take it home, which is to have a good laugh, a great gag and a stocking filler bound to force everyone to rethink of their gift-giving ideas.

Apart from a penis pasta cookery book, the rest of the "That Awkward Moment" star's holiday included a getaway with his 27-year-old girlfriend Sami Miro. According to US Weekly, the couple spent the time off sightseeing in several countries in Asia including Japan and Vietnam.

Efron was noticeably a great presence in the movie scene this year and fans will see more of him next year. Back in August, he starred in the musical drama film "We Are Your Friends." Channel 24 reported that he is currently filming "Neighbors 2: Sorority Rising," a sequel to the 2014 comedy he co-starred with Seth Rogen.

The aforementioned site also reports that Efron will also appear in "Baywatch," a movie adaptation of the drama series executive produced by David Hasselhoff back in 1989. "Fast and Furious 7" star Dwayne Johnson will be in it too along with Kelly Brooks.

However, the next time moviegoers will see Efron will be in "Dirty Grandpa" with Robert De Niro. The film releases on Jan. 22. Here, Efron plays the role of uptight lawyer Jason Kelly and a fiancé to his boss' domineering daughter. Before he ties the knot, his grandfather Dick tricks him into what will easily become the best week of his life.
