I like the quote in its use of sarcasm to emphasize a point.
I completely dislike that its apparent value also comes because it's a quote from a comedic character in a comedy film. I mean, that diminishes its value as sarcasm, and it becomes just a canned answer.
From the original(?) Swedish: "Jag är inte bara störst, bäst och vackrast, jag är ödmjukast också!"
(Non-standard use of "-est" superlative forms in English for consistency, effect, and fidelity.)
