For a complete lesson with explanations and comments check out: http://edutainesl.wordpress.com/2014/05/31/grammarwithcomix. Comic strips and jokes are used to explain the comparative and superlative degrees of adjectives. It also covers some irregular forms and changes in spelling in the comparative and the superlative degrees and as always includes a comic-strip style exercise to practice the skills. I developed this grammar show for my B1 students.
