For the government of Mexico imposes fines for individuals who perform their national anthem incorrectly.

This policy also applies to other patriotic symbols such as the Mexican flag and national seal. A recent example of this precedent in action occurred back in October at a soccer match in Guadalajara against Monterrey. Singer Guadalupe Madrigal confused some lyrics in the Mexican national anthem. She didn't do so intentionally and she apologized. After reviewing Madrigal’s financial situation, the government chose to fine her $40 - but she could have been subject to potential fines of up to $880! (The whole story) According to the government the fine was to ensure “the necessary respect that patriotic symbols deserve." Too bad the U.S. government couldn't fine Roseanne Barr for her version of the national anthem.
