You are not alone: had a physics professor who appeared to have a mental orgasm whenever spherical harmonics arose in lecture. Perhaps he also once did the "100 sheets of calculations...". Given a difficult problem, we would joke the solution was obvious - use an expansion of spherical harmonics - voila!
