Recent observations are confirming the standard lambda-cold dark matter cosmological model in a spectacular way. This is the "earworm" song playing in the head of cosmologists today. But is this true? In this talk, I will illustrate some of the tensions that are now arising between cosmological observations arguing that something more ricky could be in place.In particular, I will show how the recent Planck measurements show a statistically significant evidence for a closed universe,  possibly opening a "cosmological crisis" where disparate observed properties of the Universe appear to be mutually nconsistent.
