Are typos really typos or are they cryptic messages for us?

A friend posted Led Zepplin’s live video of Stairway to Heaven on Facebook.   We’d watched it the night before and our comments to each other were: great song, great guitar solo and wow could his pants be any tighter?   A FB friend of his posted:, “Great tune.. so love to metaphysically interpret lyrics… every dong takes on an expanded meaning…”  I agreed, “Yes and every song as well.”
