Not really, according to the advertisement wording, it gives you wiings... not wings.
Probably done for legal reasons, getting sued by people that didnt get wings is stupid, but with the way the legal system is set up in North America...
I am not sure if advertising authorities have rules about using meaningless words, even if they did, I am sure that in some language out there WIINGS means something.
If you have any info about the advertising or reason behind using wiings, please let me know.
