You know, once there was a time when we used to say, "her boobs are as big as her head!" when we referred to boobs we thought were big.
Now, when you describe the 'bigness' (biggity?) of Chelsea's boobs, you have to say they're twice as big as her head.

Chelsea has re-defined the meaning of 'big'.
Look at that pic with Rhiannon in it. If Rhiannon has 4000+cc's in each implant, how much does Chelsea have nowadays? 10000cc's? I think I'm gonna faint...
