Indigo is a tough one to pun with.
Everyone is jealous of Megan Mullally's marriage to actor, comedian, musician, meat-eater and woodworker Nick Offerman. For her 50th birthday, Mullally asked her husband for a rainbow.
Though a man of epic talents, Offerman had no way to "get" a rainbow, so he instead he wrote his wife a love song punning with all the rainbow's colors.
The song is also part of Children's Cancer Association's MyMusicRx program, the non-profit charity's effort to help children battling longterm or serious illness.
This is a good man.
