KATIE: Your Sinko???
WAFFLES: Yeah, my Sinko de My-O.
KATIE: Waffles, that is wrong on SO many levels.
WAFFLES: Whaddaya mean?
KATIE: Where do I BEGIN? Ok, if that really was your "Sinko," it's not exactly grammatically correct to say "my Sinko de My-O." That would be like saying "my treats of mine."
WAFFLES: Treats??? I don't have any treats in MY Sinko de My-O! Do you have treats in yours?
KATIE: Waffles, there's no such thing as a Sinko de My-O.
WAFFLES: Yuh huh! Today's Sinko de My-O day!
KATIE: You mean CINCO de MAYO.
WAFFLES: That's what I said!
WAFFLES: Sinko de My-O!
