We don't know about you, but once May hits, and we start feeling a bit sillier. The end of school is so close that it can be hard to focus on anything but all of the summer fun that awaits! So when we came across this photo of Lucy Hale and Ian Harding clowning around on set, we decided to take a cue from our favorite Pretty Little Liars stars, and have some fun with facial hair.

We've photoshopped mustaches on some of our favorite celebs below. Which ones do you think are the funniest?

Harry Styles

With the stache, button-down shirt, and blazer we're getting a young Sherlock Holmes vibe from the 1D member.

Justin Bieber

This mustache is a bit more grown out than the last one Justin sported.

Cody Simpson

We think Cody's a bit too young to have gray hairs showing in his stache!

Kendall Schmidt and James Maslow

The facial hair makes their bromance look so much more broey.

Niall Horan and Liam Payne

We definitely prefer our One Direction guys to be clean shaven!

Hunter Hayes

The mustache distracts from Hunter's seriously adorable dimples!

Carlos Pena and Logan Henderson

The BTR boys just can't pull off a stache as well as Zac Efron can…

Austin Mahone

Austin could totally go incognito with that hairy beast under his nose. No one would ever know it was him!

Louis Tomlinson and Zayn Malik

We think 1D should incorporate mustaches into their next music video. How hilarious would that be?

Ross Lynch

We're thinking Ross would need to dye that blonde before we even considered letting him keep it.
