Panel 1: As forworse said, it's Christmas morning and we have John playing with Mike's Super Speedway set while everyone watches him be a grinning idiot; a confused Mike asks a smirking Elly if she's sure that this was Santa's gift to Daddy. This is because, of course, the little boy thinks that since Daddy is having so much fun with it, it must be his.
Summary: This isn't the only time he's pulled this stunt. Every so often, Elly will ask one of the kids if s/he is bored with a toy only to be told that John has to get bored with it before it can be played with and eventually ignored by the person it was intended for. In this first instance, Mike wasn't aware of this so he doesn't realize that Daddy is bogarting HIS toys.
