Feeling lucky? Well Zac Efron was when he joined Jimmy Fallon on his The Tonight Show.
The host invited Zac to play a game of egg roulette yesterday.
One by one each would smash an egg (some boiled, some raw) on their head hoping it wasn't a raw one.
The first person to crack two raw eggs lose.
"You can kinda tell" if the egg's hard-boiled, Zac told Jimmy while shaking an egg in his hand before smashing it on his head.
"You can't tell," Fallon replied with a smile.
Watch the video above to see how things got messy.

Ellen DeGeneres and wife Portia de Rossi
Ellen and her wife celebrated their seventh wedding anniversary at this year's TCA looking fab in their shades.

Emma Roberts
The American Horror Story actress looking very elegant in her Peter Pilotto dress.

Fifth Harmony
More than half of the girls showing off their legs with split-skirts. Looking very sexual ladies.

Jordana Brewster
The Fast and Furious actress keeping it simple, yet effective in her Ulyana Sergeenko off the shoulder dress.

Jordin Sparks
Looking a bit Beetlejuice-esque, but we likey a lot. Jordin kept it high street in this Karen Millen.

Lea Michele
We love that Lea matched her red show with this Monique Lhuillier. Absolutely gorge.

Little Mix
For one the four-some aren't doing that girl-band matchy thing they do. We love Jade's shirt-dress.

Lucy Hale
Bit of mesh to cover an accidental boob-slip from happening is working wonders for Lucy in her Julien Macdonald.

Nina Dobrev
Oh so sexual in this split-fabric dress by Zuhair Murad.

Peyton List
The Remember Me actress looks smoking in, possibly our fave outfit of the awards, in her Diane Von Furstenberg.

Rita Ora
The lady in red killed it in this red-suit by Max Mara. LOVE. We better see lots of outfits like on The X Factor this year Rita.

Sarah Hyland
So sweet in Christian Siriano with her matching clutch.

Victoria Justice
Jade colour dress by Herve Leger is tassel-licious.
