  Extensive efforts have been made to understand the electronic properties of
high-Tc superconductors. One feature which has been discussed in the literature
during the past few years is the dips in tunneling conductances obtained in
cuprates. In this contribution, we focus our attention on the origin of these
dips. On the basis of experimental data obtained in Bi2Sr2CaCu2O8 and
YBa2Cu3O7, we show that the dips appear naturally in tunneling spectra due to a
superposition of the peaks and humps and, therefore, have no physical meaning.
