Regarding your post “Commercial Bliss” at the Corner, after reading it I was reminded of how bizarre I thought it that KY is explicitly referenced on the TSA website as an approved carry-on item.
Baby formula, breast milk, and juice for infants and toddlers.All prescription and over-the-counter medications (liquids, gels, and aerosols) including KY jelly, eye drops, and saline solution for medical purposes; Liquids including water, juice, or liquid nutrition or gels for passengers with a disability or medical condition; Life-support and life-sustaining liquids such as bone marrow, blood products, and transplant organs; Items used to augment the body for medical or cosmetic reasons such as mastectomy products, prosthetic breasts, bras or shells containing gels, saline solution, or other liquids; and, Frozen gels/liquids are permitted if required to cool medical and infant/child exemptions. Frozen gels/liquids for any other purpose are not permitted.

That’s a whole different kind of homeland security.
