staled

With him it was one favorite little joke which never staled.

His aging muscles, staled by thirty-odd years of lack of practice at such tricks, merely made it jerky and forced.

It is a matter of fact that besides being most intense, it is most enduring, growing, and never staled by custom.

The game of prying fork-tines staled on them one by one, and they took to songs, mostly of love and parting.

The humour of this joke never staled, and they parted with hoots and guffaws of laughter.
