A, B or C

Phrases I am unlikely to say sincerely,

A)
"C'mon, if you think you're hard enough. I'll F***in' deck you"

B)
"I love you more than I would love a four liter tub of ice-cream and my doc martens combined"

C)
"Van Gogh was a drunken moron and Andy Warhol was a catholic twerp"

Which is least likely? Cast your public or private opinion to either everyone or yourself.
