Comedy about group of inept assassins?

Turning up to kill without any real plan, turning up as back up killer without any real plan, wearing a big black coat over camouflage, not wearing a bulletproof vest under camouflage, sneaking up on people in really loud shoes, constantly losing the element of surprise, not checking if your gun works, getting your gun stuck in your seat belt, leaving people in cars with their neck broke, chucking your dirty mobile out of a moving car window, perching on sloped roofs with a big drop underneath, paying people youre meant to be killing

Classic comedy device at the end when the girl gets her eye blacked up and spiky hair after clooney shoved a banana in her muzzle so she'd blow her own face off. Seriously, was that not a hat tip to roadrunner?
