To be fair Foxi4 said "gets" the reference. In my experience the difference between those that have heard of it and those that know what is pertains to enough to "get it" is probably second only to e=mc^2.
Ain't that the strange symbolmagis that one old geezer used to write on blackboards?
Besides, you should be more inclusive towards photons (the boson that sometimes self identifies as a lepton) and use the PC (Physcal Correct) expression E = sqrt( (m_rest * c²) + (p * c)² );
