When she told me, I knew there had to be more to it, so here, in its entirety is the song. I would sing it, but I'm unable at this time to embed an audio file in this blog.
I chased a bug around a tree,
The biggest bug you'll ever see.
I bagged that bug, 'cause he bugged me,
That bug around a tree.
A bug... a bug... a bug... a bug...
A bug around a tree.
I caught that bug and asked, "Tell me,
O bug, why do you pester me?"
He said, in all sincerity,
For cu... for cu... for cu... for cu...
Now go and sing this song to any children you know who are bugging you, and require some bugging in return.
