Dynamite is an explosive made of nitroglycerin, sorbents (such as powdered shells or clay) and stabilizers. It was invented by the Swedish chemist and engineer Alfred Nobel in Geesthacht.
Besides Foxy Grandma, June Foray also voiced Rocky The Flying Squirrel and many other cartoon characters, and was known as the Cartoon Queen.
Foxy Grandma passes the bank teller a note that says "Have Dynamite You'll Travel," which is a play on the TV show Have Gun-Will Travel starring Richard Boone.
At the end of the episode, Wilma invites her mother to stay with them until the baby is born; however, in the previous episode, her mother had already come to stay with them.
