"Good to the last drop” is a trademarked slogan of Maxwell House Coffee, “Skydiving/Skydivers—Good to the last drop” is a jocular saying that has been printed on many gift items, such as posters, T-shirts and bumper stickers.
“Good to the last drop” was printed in a newspaper skydiving story in 1980; bumper stickers with the saying have been printed since at least 1994.
