2x genitive

[Nightmare85]

Hello guys,
Do you think it is okay to use the genitive twice?
My brother's friend's dad has birthday tomorrow.

Should we better avoid double genitives?
The dad of my brother's friend has birthday tomorrow.

What would you choose?
I have no idea :-o

Cheers!

My brother's friend's dad has (a)(his) birthday tomorrow.

You could also say "It's my brother's friend's dad's birthday tomorrow." But don't have 'too many' possessives, as it would become hard to follow.
