Advertisement-Liquid Paper

My favorite advertisement was about "Liquid Paper". It's about 2 people, they are talking; and in the middle of the conversation, one of them says: "Look that pretty woman", and the other answer: "That's my sister". (Meanwhile a voice said: "Error"). And the other said again: "No, the other", and the other man answered angrily: "That's my mom!!!!" (The same voice said again: "Big Error". "For not having this mistakes buy Liquid Paper, now 2 in 1"). In my opinion, this is the best advertisement because, it't for all ages, everyone can understand it, and have sence of humor. Also because is so funny, when one of the mans, says angrily: "That's my mom!!!!", and he go to hit him, while the other run away.
