Me and my bloke were playing this game a few days ago and I thought it was really good fun.
You've got to think of two celebs who would make a great double barreled name if they got married (or had a civil partnership!)
For instance,
If Anthony Head married Cilla Black, they would be
Cilla and Anthony Black-Head.
Or
Ed Balls and Heather Small =
Heather and Ed Small-Balls.
Any more? (you can use the same person more than once).
