Halloween

One Arizona prankster is putting the trick in "trick or treat" ... donning a Michael Myers mask to scare drivers stuck in standstill traffic.

Check it out ... the unnamed culprit is seen wearing dark coveralls and the signature mask of the murderous villain in the "Halloween" horror franchise ... best known for starring Jamie Lee Curtis.

In a video making the rounds online ... the masked rascal carries a fake knife while creeping up on cars stuck in a nightmare traffic jam north of Phoenix, Arizona.

Here's further proof Josh Allen and Hailee Steinfeld's relationship is pretty serious ... the two threw on a couples' costume and hosted a huge Halloween bash for all of Allen's Buffalo Bills teammates.

The party went down on Monday night -- and it was officially dubbed "Josh & Hailee's Circus Showdown 2024."

Allen wore a ringleader red coat and black top hot for the occasion, while Steinfeld wore a similar -- yet far sexier! -- get-up.

Before this cute festive kid with face paint turned into an American YouTuber and singer, he was just 15 years old, starting his YouTube channel, before heading off to Hollywood to start his entertainment career.

While his early content consisted of baking and his everyday life in small-town Texas, he now has garnered millions of views, like his "Heather" music video, which has over 172 million views.

He's a known "Swiftie," and when he dropped his "Kid Krow" album, he got a personal shoutout from none other than Taylor herself!

Cleveland Browns superstar Myles Garrett's Halloween costume got the ultimate compliment on Sunday ... with none other than Arnold Schwarzenegger praising his Terminator outfit!!
