Anyway,
I've done 3 Cadbury's Cream Eggs at once. One in each cheek, and one rammed in the middle. And lots of tongue action trying to break the chocolate.
Apparently the girlfriend of the time didn't find it quite the aphrodisiac I was hoping for at that moment.
I don't believe it's physically possible to beat that without breaking the eggs to start with.

I am impressed.
How long did it take you?I think four could be theoretically possible if you tilted your head backwards and allowed the additional egg to just balance there while you tounged down the ones in the mouth. Would that be allowed?
I'm not too sure given that a) it was a fair while ago. And b) I had imbibed more that 1.5 times the diving limit of snakebite, which was the obvious drink of the day.
