Squirrel- "Hey I don't collect shoes but I just copped those new super rare Air Jordans that came out today. I know how much you wanted them so I got them for you in your size!"
You- "oh really? Awesome! How much were they? I'll hit you with some extra cash for hooking me up"
Squirrel- "They were $230 but instead of putting them on Ebay and being a dirty re-seller I'll give them to you for the "friend price" of $800..."
You- "... wow, what a great friend..."
