Now the rest of your life will depend on whether you have fun by being nifty, or you become bored by being thrifty. The choice is yours. Happy birthday.

Yes, 50 is nifty… if you're rich, slim, beautiful and famous. Happy un-nifty 50th birthday!

You’ve got half a century of accumulated knowledge and wisdom! That would be awesome… if you could remember any of it.

You know you're 50 when someone offers you a seat on the bus. And you don't refuse.

Don’t worry about getting older. You can still go for facelifts to wipe out the wrinkles. Happy birthday!

You know you're 50 when a kid you once babysat is now your lawyer

Happy birthday to someone who's 50 in body and 15 in mind.

It is never too late to grow up and stop being stupid. Maybe your 50th birthday is your chance to do just that. Happy birthday.

You know you're 50 when you have a party and the neighbours don't even realise

You know you're 50 when someone offers you a seat on the bus and you don't refuse.

You know you're 50 when your back is hairier than your head

You know you're 50 when you have a party and your neighbours don't even realise.

The older you get, the brighter your cake becomes. See? It’s all filled with burning candles. Have fun blowing!

It's amazing how good you look for your age considering everything we've been up to over the years. Happy 50th!

You can’t hide your age to others. Your hair is turning gray, and wrinkles appearing. So, tell the truth, is it your 50th, or you’re lying.

At our age we've seen it all, heart it all, done it all. We just can't remember it all! Happy 50th birthday and cheers to many more memories we might forget!

Thanks for reminding me that I’m not as old as you. Happy Birthday you old fart!

Forget age. If you can still manage to blow out your birthday candles, everything is dandy! Happy 50th birthday!

I hope you already saved enough money for retirement. It’s time to count them all. Happy 50th birthday!
