fun with the pharmacy:

Alacrity: "I'm here to pick up the melanoma vaccine for Sadie."

Pharmacist: "Do you know that Sadie is a horse?"

Alacrity: "Yes...I wrote the prescription."

Pharmacist: "Well, the melanoma vaccine is only labeled for dogs."

Alacrity: "Yes, it is."

Pharmacist: "So you're using the vaccine off-label."

Alacrity: "Yes, I am."

Pharmacist: "Well, a horse is much bigger than a dog."

Alacrity: "Yes."

Pharmacist: "I just have to tell you that you're using this product off-label."

Alacrity: "Yes, thank you. Message received."
