Looking out for their best interests

Jordon and Mark are at Dairy Queen and Mark notices that Jordon’s cone is bigger than his.

Mark: Umm, Dad, how come your ice cream cone is bigger than mine.

Jordon: Because I am bigger than you are.

Mark: Aren’t you diabetic

Jordon: Yes

Mark: You shouldn’t have a big cone.  Let’s trade.

Jordon: How do you know my blood sugar isn’t low?

Mark: Nice try Dad.  I’m telling Mom.
