Wedge...

Coincidence: You take a picture of a Trivial Pursuit wedge which is along the same design aesthetic as Pacman. Only later do you realize that Mr Pac is celebrating his 30th anniversary just now. In fact if you want to be a bit morbid about it, the wedge looks like Pacman in his death throws.

Ironic Coincidence: The answer to the question, "What became the must have toy in 1998?", is The Furby, you get it wrong but your play piece is sitting on a picture of one.
