Happy Birthday to you, happy birthday to you!
Happy birthday, dear KJ, Happy birthday to you!
How old are you now, how old are you now?
Better hurry up and find a husband, before your ovaries fall off!
TEEHEE!
Actually, that is wrong, because it is not a Latin noun of the second declension, but rather a Latinized form of Greek ὀκτώπους. The theoretically correct plural would be octopodes.
I'm fairly sure that both Loti and Lotuses are correct (as in, you can use either), but octopi is just plain wrong
