I guess it's the fact that the man now has a handsome face, but still on a - shall we say - slightly lumpy body? I'm sure there's a more in-depth explanation...
I can't believe anyone could think that man handsome. He gives me the creeps! Shudder to think what he must have looked like before the plastic surgery.
Just that it's a more than ok improvement, one is expected to assume he was ugly before and the results are better than expected. Supposedly demonstrating the Yorkshire tendency to understatement.
You see him from the back looking plumpy, a bald patch and presumably of a certain age and then he turns round with a young face and designer stubble. I must say I found it obvious.
