Is Magic Real?

S1 E4: When an old wizard seems to have lost faith in the existence of magic, Mike thinks he can prove him wrong — if he can just find a leprechaun he met years ago, one night at a bar. Along the way, Mike manages to beat up an illusionist and an actor, in separate incidents. In the end, Mike learns you don't need to find a leprechaun, because there's a leprechaun inside of us all.
