When did Johnny wake up?

Kindergarten Teacher: OK class. If you went to sleep in 1970 what year did you wake up?

Kid 1: 1970.

Teacher: OK anyone else have an answer?

Kid 2: This year - 2017.

Teacher: Why do you say that?

Kid 2: Because the bed was called a 1970 cause that was when it was made.

Kid 3: Because you pooped yourself and it took them until 2017 to remove the stain

Teacher: Where do you get these answers...?
