We just read that to the tune of "Bye Bye Birdie" and that's what we'll do all day now.

When picking a goodbye cake, the important thing you want your departing coworker to know is "we actually know who you are and aren't just showing up to this party for free cake." Whether the feeling expressed in the cake is positive or hateful is secondary; after all, hate is not the opposite of love, indifference is. Deep. This cake will let your about-to-no-longer-be coworker know that you were certainly never indifferent to them, and indeed that their actions here today are filling you with great joy.
