Some infrequent, mild sex references. Nothing noticable.

2 Men get impaled by an mechanical mosquito.

A teenage boy gets electrocuted.

Two uses of "fuck". Plus, some mild language like "hell", "damn", "asshole", "shit" and "bitch".

I dunno, probably just some smoking.

Despite the try at scares, most of them is hard to take seriously and come off as rather comical. Some young kids may be creeped out.
