Toast to My Brother on His 21st

Hi guys I’m in desperate need of some help!!!!
I’m trying to write a toast to my brother on his 21st and I want it to be real funny but also special. I’ve read your posts and started by talking about events of th year, and ended with what a wonderful person he has become, but I’m hoping for a quick joke to add some meat to the centre of the toast. Can’t use funny event of his life, cos there aren’t very many that you repeat in front of people! PLLLEEEAAASSSEEE HEEEELLLPPP!!!!

Here are a few that could work

"Artificial intelligence is a wonderful thing. I told my computer that today is my birthday, and it said that I needed an upgrade."

"A true friend remembers your birthday but not your age."

"Growing old is mandatory… growing up is optional!"

Here is another one that could work for your brother. If you are older you could put yourself into the joke – if your brother is older you could put him into the joke.

A mother asked her small son what he would like for his birthday.

"I’d like a little brother," the boy said.

"Oh my, that’s such a big wish," the mother said. Why do you want a little brother"?

"Well," said the boy, "There’s only so much I can blame on my dog."

Perhpas you could say that. (I mean that the funny events in my brothers life aren’t ones that I can repeat. so let me tell you about ones that didn’t happen, etc.)
