Bloke takes pet duck to Vet. Vet lays duck out on table, pronounces it deceased. Bloke is very upset. 'Are you sure?'. 'Well, I can get a second opinion', says Vet. 'OK', says Bloke. Big brown Labrador dog walks in, looks at duck, shakes head and walks out. A cat comes in, jumps on the table, looks the duck up and down and then leaves the room. Vet prints out the bill on his computer, gives it to Bloke. '$200!' exclaims Bloke. 'Why so much?' 'Well,' says Vet, 'it would have been $40 without the Lab Report and the Cat Scan'.
