Cry me a river.
A few more hilarious ones, which you may prefer choosing.
"Cry me a river, build a bridge and get over it."
"Cry me a river, build a bridge and help traffic congestion."
"Cry me a river and drown yourself."
"Cry me a river and drown your sorrows."
"Cry me a river cos the council won't build me one and I've asked heaps of times and they keep telling me to send money in and I promise them the money so they say they'll get estimates and then I wait and nothing happens and I'm getting a petition signed so could you sign this for me? . . . Thanks and anyway they keep telling me that it's a bad catchment zone so a river is a bad choice so I got the map out and told them it was a good place for it and they could even put a dam further down to help the town but they just said they'll get estimates and I've sent some money in but they haven't replied so do you reckon if I make you really really sad you'll cry me one?"
"Cry me rapids, go tubing, and get happy like the rest of us."
"Cry me a river, save Australia."
When I said that we pride ourselves on them, I was thinking if they were witty and original and actually had some use. I can give and take flak well, but that's just boring mate.
Oh, and a mandatory fuck you, for dignity's sake.
EDIT: Nobody has said that my above ones were funny. I made them all up too. This makes me sad.
