Bliggy, Blaggy, Bluggy Tony!

• TKIC watches the Teletubbies while playing with his toys.  Dad had thought that Tony was over that stupid show!
• Tony picks up his father's reading glasses case, which had been left on the dinner table.  Tony puts the case to his ears and begins to talk.  Dad, who sits and reads, at first thinks his son has someone's mobile phone.  But Dad looks up to see Tony holding his reading glass case.  Dad demands the case back and tries to catch Tony who happily dodges Dad's grasping hands.
• Tony puts his die cast metal train engines sofa.  He then pushes the toys off and they fall on the floor.  Why?
