16 is not for the fainthearted because from 15 you have departed, and guess what? You’re only getting started! Happy Sweet 16!

You will have many opportunities to demonstrate your maturity as a near-adult, but why waste your childhood on that? Happy 16 B’day!

I have two tips for you on your 16th birthday. One: forget the past because you can’t change it. Two: forget the gift because I didn’t get you one. Kidding! Happy birthday!

Being 16 is wonderful because you can conveniently act grown up and dumb as when you need to. Enjoy this phase of life while you have it. Happy Birthday.

Why does this keep happening? I’m going to find a giant maze and kick someone’s ass in air hockey in your honor.

It took you 16 years to come as perfect as you are. Congratulation and have a great day.

You might be getting birthday gifts on your 16th birthday, but your auto insurance company is getting a birthday premium, too.

I have a joke for your birthday: It’s hard to explain puns to kleptomaniacs because they always take things literally. Happy funny birthday my friend!
