Reflexive Pronouns and Objects of Preposition

Ha! A reflexive pronoun gets mistaken for the object of the preposition.

Normally, the "yourself" would emphasize the fact that the character is doing all the work. Grammatically, it probably should have read "are you putting them up, yourself."

Instead, in the final frame, "yourself" is treated as the object of the prepositional phrase "up yourself." This indicates the location of where the lights are being put, resulting in a humorous and grim scene.

I see what you did there.
