"How are Things in Guacamole"
Dad used to mangle song lyrics for comic effect but took Gershwin and Cole Porter very seriously. He'd been a crooner in college and his favorites seem to be "But Not For Me" and "I Get a Kick Out of You" among others.
He also became a Kingston Trio fan when they first appeared and used to sing their version of "It Takes a Worried Man" when we did projects around the house.
