'Well I'll be damned': McDonald's swears its 'Minions' Happy Meal toys don't curse

McDonald's swears up and down that the little yellow "Minions" Happy Meal toy is speaking only nonsense words and not something a little more adult.

Experts say the company may be right, and the fault may lie in how our brains are primed to find words even when they're not really there.

The world's largest hamburger chain and purveyor of Happy Meals said it doesn't plan to take the talking Happy Meal toy out of distribution, even though some customers say it sounds like it's cursing.

Some customers said the toy makes a sound that could be interpreted as the phrase often abbreviated as "WTF". Another phrase sounded like it could be "Well I'll be damned".

The little yellow Minion characters speak a nonsense language and McDonald's said the Minion Caveman toy makes three sounds - "Ha ha ha", "Para la bukay", and "Eh eh". The company said it received only a few comments from customers about the toy, which was introduced on July 3.

Nonsense speech will sometimes sound a bit like a real language, and experts say human brains are also wired to look for meaning in noise and images.
