Possible reasons for this woman having "Whales" painted on her face at a Wales game include:
1. Intentional pun.
2. Complete misunderstanding of how 'Wales' is spelled.
3. She's an animal rights activist whose aim was to get on TV to show her support for Whales.
4. It's guerrilla advertising for the Discovery Channel show 'Whale Wars'.
5. She just loves Whales.
6. Somebody who dislikes her did the face painting and she hasn't checked a mirror since.
7. Everyone else has been spelling Wales wrong all this time.
