Why do people say "I'm happy as a clam"?
That doesn't seem very fun, laying around all day, eating................
Oh wait, that DOES seem fun and enjoyable..
Or what about "a piece of cake" cake sucks, it can be difficult to make a decent cake (From scratch).
So if you're going to say something that ABSURD you could just say "a piece of pie" since pie beats cake hands down....
And if you ever see me playing the TCG and I'm taking a very long time it's not about my next move if I should play 2 crobat G or risk using hurricane punch it's really about the above 2 statements...
