Wanttobehealthy, that is a really good one!
Quack, quack, quack, quack, quack!!!
A joke: A duck walks into a store and says "Hey buddy, got any corn?"
The store owner says "No, duck, and if you don't leave now I'll nail your flat feet to the floor!
The next day the duck walks in and says "Hey buddy, got any nails?"
The store owner says "Well...no...we don't carry nails."
To which the duck says "QUACK! Got any corn?"
