'Weird Al' Yankovich has a grammar lesson to teach you.

This is the second spoof video in two days that Weird Al has released off of his newest album , "Mandatory Fun." Set to the tune of Robin Thicke's 'Blurred Lines,' 'Weird Al' attempts to educate us about participles, contractions, nouns and prepositions.

Grab a seat and take out a few sheets of paper from your college-ruled notebook. Pay attention!
