For people you don’t actually like, who have young children.
The “Yellies,” as they’re appropriately named, only work when your children scream at them.
The louder the voices, the faster the furry creatures go.
Kids can even trigger something called “freakout mode,” which only happens when little ones really ramp up the shrieking.
As you might expect, parents aren’t so thrilled.
It is a toy which encourages children to yell more. Designed by evil people.
That reminds me of the time I gave my brother’s boy a toddler karaoke machine with an amplified microphone.
