Happy

The following conversation occurred in our house this morning. The names have not been changed to protect the innocent.

Alli: (calling from the kitchen) How's Caleb doing in there?
DJ: He's happy.
A: Happy as a clam?
D: Are clams really that happy?
A: They must be!

A little later in the morning...

DJ: (looking at Caleb playing with his kick gym) Look at him! He's as happy as a lark!
Alli: Are larks happy?
D: They're as happy as clams I suppose.
A: What other animals are happy? I mean, can you be as happy as a giraffe?
D: I don't think giraffes are happy.
D and A: (in perfect, spontanious union) Aww, poor giraffes!
