Hungry for banana shake

I don't know why but all of a sudden i want a banana shake but i don't want to go buy one. I want to make one from fresh banana's. I'm just craving for one so bad right now. We don't even have a blender so how am i going to do it? That's so crazy huh. I know you must have a blender to make any kind of shakes or smoothies. I'm just so craving for one right now. I asked my wife if we can go to walmart and pick one up but she didn't say anything so i don't know. Maybe it would be cheaper if we just go drive down the street to Carl's junior and buy one huh? You think?
