That's the question for the National Zoo and Aquarium in Canberra which on Saturday is celebrating the 19th birthday of one of its favourites, Hummer the giraffe.
And everyone is invited to the party.
Hummer celebrated his birthday during the week, but celebrations will continue on Saturday at 11.30am when Hummer gets a special present from his keepers and a cake which might just contain at least a hint of lucerne and carrot.
Hummer is a long-time bachelor, never siring a baby, but has a new best friend in Skye the giraffe.
There will also be activities happening both at the zoo on the day as well as through social media.
