Feynman diagrams, Gaussian integral, moments, propagator, asymptotic series.

We examine the moments of the Gaussian integral and relatethem to Feynman diagrams. We next introduce a quarticterm and show how it leads to a seemingly paradoxical result.The article is addressed to the novice, but we believe that itmay also serve as an opening lecture on the topic of Feynmandiagrams.
