Seven Footballs

I'm sure no mother has ever had to put up with this! My son has had a parcel sent to our hotel in Houston. Fine Matt, not a problem.
So the box arrived on Monday. About 12" cube. Almost too frightened to open it, but hey, I'm brave-ish.
Inside the box were seven footballs. Yes footballs. Those oval things that we won the World Cup with.
Matt found a website selling them off and he thought he might need them. They have the flags of various competing countries on them.
Next question - how do I fit them in my suitcase. Yes, they are deflated, but they still take up a lot of space. Similar to seven pairs of shoes.
Don't you just love kids?
