Silly Compliments

Silly compliments are paid either out of nastiness or out of boredom. Sometimes people who pay silly compliments are just very bad at complimenting, that's why their fitful attempts to express their appreciation to a female result in nothing but silliness.
Real life examples of silly compliments are: 'you have nice knees', 'you have good breath', 'I like women with a little grey in their hair', 'you look like my ex-wife', 'you're my lovely penguin'... The list could go on forever for so many weird or silly people, so many compliments of equally interesting characteristics.
How would you react if you were told at a nightclub that you had nice breath? A quite difficult question, isn't it? Because you know perfectly well how to react if you are told about nice tits, ass or alike things, but when it comes to your nice breath comments, it is weird enough to leave you totally speechless...
I-like-women-with-grey-in-their-hair compliment is on the border between silly and totally stupid one. It can be quite offensive, especially if you pay it to a woman who doesn't possess a very unique for most women ability to laugh at themselves.
Regarding the penguin-attempt-to-compliment or heck knows what, these things are very individual, maybe there are people who would love to be called penguins. But the point remains stably unchanged – it is very silly (to put it mildly).
