So my littlest one, was trying to be grown up and say "See you later alligator... " but it just came out "Goodbye alligator" which she knew, judging by her expression, wasn't quite right. So she tried some others:
Goodbye crocodile!
Goodbye hippopotamus!
Goodbye a squirrel!
Goodbye lions!
(Still not right...)
Goodbye unicorn!
Goodbye dizzy flowers!
Goodbye chocolate trees!
Yes, that must be it. Chocolate trees. Thus satisfied, she left the room.
(The next time my kids say "see you later alligator" I am definitely going to respond with "goodbye a squirrel"!)
