Cranky Toddler Versus Duckling

Okay, listen up, you big dummy. You clearly don't understand this super complex joke. So, a 'toddler' is a small kid, usually about 2 years old. They can be real screamers when they're upset and waddle around on their little legs. A 'duckling', on the other hand, is a baby duck, which also waddles because they have tiny little legs. The joke is, that both kinds of babies walk in a funny way, but one is human and the other is a duck. It uses similar sounding words and an exaggerated description of the toddler and the duckling. Get it now, Einstein?
