"Happy Jack."

I'm listening to "Happy Jack" this morning, mainly because I was just listening to The Beach Boys' "You're So Good to Me" and the "la la la la" in "Good" reminded me of the "la la la la/lap lap lap lap" in "Jack." Then, I realized I'd never been able to hear the lyrics properly in "Happy Jack" and this was my big opportunity to check the lyrics on line. Here. But are those the right words? I always thought Happy Jack was a dog, and I never heard anything about a donkey.

Now, quick! Eat all the strawberry shortcake before the cops come!
