We often assume that we observe the universe the way it is there, but actually there are things happening to light between there and here. An important such effect is gravitational lensing, which affects all observations made across our clumpy universe. In my talk I will discuss some recent results on the impact of lensing on number counts, and some ideas on how to extract the lensing information from such observations.
