A rip in the time-space continuum causes a Celtic bard and Donkey from "Shrek" to be sucked into the "Star Wars" universe. (You can tell this is going to be a serious joke).
They are met by Luke Skywalker who insists that the bard should write a song about Yoda.The bard explains that he can only write lays, a kind of primitive poem, but Luke says that's ok. So the bard works day and night, with Donkey's help, and finally is ready for the recitation - which goes as follows:
Bard: Yoda lay--
Donkey: Hee haw!
Bard: Yoda lay--
Donkey: Hee haw!
Everyone thinks this is a scream, so the bard is emboldened and really goes for it:
Bard: Yoda lay, Yoda lay, Yoda lay, Yoda lay, Yoda lay, Yoda lay, Yo--
Donkey: Hee haw!
Bard: Yoda lay, Yoda lay, Yoda lay, Yoda lay, Yoda lay, Yoda lay, Yo--
Donkey: Hee haw!
Bard: Yoda lay---
At this point, Luke pushes them both off a cliff and they fall screaming to their deaths. Everyone is shocked, but Luke explains that this is supposed to happen.
*jumps in a spaceship and flies away to avoid being lynched for the silliness*
Being an uncle, I occasionally have to tell my little niece 'uncle jokes' - so I thought this one would be good for that.
