"Does I know?" - when she is trying to check if she knows the secret.
"Pick up me" - Guys pick up her instead of pick her up.
"Applecombi and Fitch" - Sounds delicious with green, red and pine apples =)
"Fox and spoon" - What is the sly one doing with a utensil?
"Big middle small" - Translation of 大中小
"Goggle is my best friend" - Usually is Google, but I suppose she is going for a swim. And perhaps with just one side of the goggles.
"wearing sch then ma so just sit on the bed la" - I can't find the typo, and completely cannot understand this. Its poor Singlish at best. Maybe I should take Comms studies haha.

Some classics that a future primary school teacher said. Quite entertaining actually =D
