Comment on "Multiple Bosonic Mode Coupling in Electron Self-Energy of (La$_{2-x}$Sr$_x$)CuO$_4$"

We calculate the photoemission spectral response using the extracted $\alpha^2F$ of Zhou et al (cond-mat/0405130) as an input and we find that the reported Re$\Sigma$ has more strucure than physically possible. Therefore, the "fine structure" most likely reflects the experimental noise.
