It's pop quiz time again! Last week Mario and Courtney went head to head in a quiz about Christmas song lyrics and for the first time ever they tied! So we have to break the tie today and see who knows the most about Christmas songs. Frasier reads the first line of the song and they have to guess it correctly. Check it out below AND tweet us some pop quiz ideas! You idea may just inspire our next quiz! @ONWithMario on twitter!
