The creepiest such encounter happened just the other day, not far from campus.
"Hey girlie, you want some *talc*?" He said that word, "talc", as if it were the most heinous, forbidden, desirable silicate on the planet.
I kept walking. He was persistent. "I said, do you want some TALC?"
"I heard you. No. Thank you. No."
"Lady, you don't get it. TALC! Four atoms of Magnesium. Three Silicon--"
"I know the breakdown. I don't need any talc!"
Then he got real close and brought his face down right next to mine and said, "It's *DRY*!"
"Leave me alone. I *know* it's dry. I don't need any fucking TALC!"
He looked completely dejected.
I looked at him and smiled and said, "But I *could* use some Lysol."
He beamed and we shared an unspoken vow of lifelong friendship.
