Comic Strip Laughter: Doug's Playful Noises Turn into Hilarious Charades for Sophie in "Dog Eat Doug"

In the first panel of today's comic strip, Doug makes funny noises and Sophie thinks they are playing charades.
In the second panel of the comic strip, Sophie guesses Doug is imitating an airplane, a motot boat and a motorcycle.
In the third panel of the comic strip, Sophie guesses Doug is an eagle with spitting issues.
In the fourth panel of the comic strip, Sophie checks Doug's diaper and realizes Doug is a baby with a fruit icy in his diaper.

Makes you wonder how it got there. Then again, if you have a baby, things like this stop surprising you after a while.
