What to get the Old Tarf?

It's the Old Tarf's birthday today and I have struggled to know what to get him.

I thought about getting him some booze, but realised he's got enough of that.
drink!

I considered getting him some plants, but the only thing he can water now is his jumper when he drools

So I got him what every man wants... a luxury bath from a beautiful geisha girl.

See how happy he is?
