I just choked on my coffee. I thought of a grossout idea. THe doctor pushed the tip of the scalpel in and the fluid streamed out. Now being a war vet the doctor knew what must be done and in advance had his stuff ready. He drops the scalpel and grabs a slice of bread and puts it under the stream and says with a sparkle in his eye and in a jovial voice "Now who wants strawberry and who wants grape jam".
