While not perfectly matching, the initial chords of  "You Like Me Too Much" and  "Something" are very similar. Observe the two graphics below. The first is the beginning of "You Like Me Too Much", the second the opening of "Something".

And to sonically illustrate, here is an audio clip layering the two:
