Envelopes of the veldt

Marcus is reading a series of books with titles like Dolphins at Daybreak, Tigers at Twilight and Buffaloes at Breakfast Time. We were all discussing these in the car the other day, and making up new silly ones. Narwhals at Noon, Egrets at Easter. Michael suggested Envelopes in the Evening, which I thought took things in new and edgy direction, into stationery. Then he said "No - what are those things called? ANTelopes, Antelopes in the Evening."
