Zac Efron's Halloween costume has legs!
The 24-year-old stud showed off his man gams last night while dressed as the short-shorts wearing Lieutenant Dangle from "Reno 911."
Joining him on the fun: Aly and AJ Michalka, who dressed as a Cigarette Girl and the Queen of Hearts.
The two pop stars/actresses also shared a photo on their Twitter of them hanging out with Miley Cyrus -- who had some crazy makeup and flaunted some serious cleavage.
