Lost My Marbles

I seem to have lost my marbles I've looked high and low Now I'm in a panic... Where did my marbles go? It wasn't very long ago That I thought I was switched on But I dropped the bag And now they have all gone I'm anxious to retrieve them If you see them let me know My marbles are important I'll reward a lot of dough What's that you say? A big reward I'd give to you? Have I lost my mind? Well... yes, I have - it's true!
