One of my "standing on one foot while answering a humungous theological question" podcasts.  "Rabbi, what do we mean by miracles?  What is up with the Red Sea splitting?"  I give my on-one-foot 5 minute answer, but we should all go and study (as Hillel famously said after answering his on-one-foot answer) afterward.

By the way, I refer to seeing a red butterfly in the answer:  at a funeral and shivah I officiated at, it came up repeatedly that a butterfly would show up in their lives just at the time of remembering the widow's husband, who had a very special connection to butterflies.
