Joe Jonas is celebrating his 27th birthday today (August 15), and no matter how old you are, you can count on your siblings to embarrass you. Nick Jonas fulfilled his brotherly duties with an adorable throwback photo on Instagram.

Both boys are too cute for this world, but it’s their hair that will give you intense ’90s flashbacks to your mom cutting your hair in your kitchen sink.

“I think you need to bring this haircut back Joe,” Nick captioned the pic. “Happy birthday bro. Love you man.”

It’s unclear why Nick was spared the fate of a high-fashion bowl cut, though I’m guessing it’s because his hair wasn't long enough back then. So could this mean the “Close” singer also sported a bowl cut later on? Nick, please confirm — with photographic proof, preferably.
