My latest earworm is driving me nuts, not because of the tune but because it's wrong.
Isn't it ironic, don't you think? It's so ironic, I really do think.
It's like rain on your wedding day. (That's NOT ironic, that's a bummer)
It's a free ride, when you've already paid. (Again, not ironic, just unfortunate)
It's the good advice, you just didn't take. (not ironic, just stupid)
...
This is driving me nuts! Please somebody, tell me there is some example of ironic in that song somewhere before I go insane.

Maybe this
as the plane crashed down, he thought "well isn't this nice". - maybe that's ironic??
