I thought it was very clever and funny, because it's something everyone can relate with, but hardly notices that they can. It was very well done and probably hard to portray.
That particular scene showed one of those daydreams you have when your mind has absolutely nothing to hold on to. The fantasy lost its "grip" the moment he forgot the concept of Benjamin Button. He imagined himself old, then younger and then old again. Then he thought that the concept was getting older but just smaller and the ridiculous romantic scene began where also odd things were said "you can just nestle in my arms and die".
I thought it was great because it shows those brief totally random daydreams everyone sometimes has and usually quickly forgets, and the way the random thoughts were chained also felt really typical.
I loved the scene. Its brilliant that he hadn't actually seen the film and only vaguely knew what the story was about, and how that vagueness literally looked in his fantasy.
I thought that scene was hilarious, I haven't laughed so hard at a movie in years at that...just wondering if you saw Benjamin buttons...I probably wouldn't have thought it was very funny if I hadn't seen that movie...
