The thing is, though, that the top and bottom halves of her face are telling different stories. Judging just by her mouth, she could well be singing - hell, she could be singing the lead in 'Carmen', considering how far open it is - but look at her eyes. Those are THOUGHTFUL eyes, not singing eyes. THEY fit the thought balloon perfectly, but then you have the mouth, and it bungles everything up. The eyes are saying 'hmm, what peculiar animals', while the mouth is saying 'La-LAAAA!' or 'AAAAAA!' or something. It just makes me wonder what on Earth the context of the original image is.
