A guy goes to a proctologist ... ... and says "Doc, I'm feeling a bit uncomfortable down below. Would you take a look?" He does. "Incredible!" He exclaims. "There's a $20 note lodged there." He eases it out with some forceps, and immediately a $10 note appears. "This is amazing", he says. "What do you want me to do?" "Yeah, well take it out, please, doc, would you?" He does, and notes continue to appear one after the other, all of which he removes. Finally there are no more. "Ah, Thanks, doc, I'm feeling much more comfortable now. Out of interest, just how much was there all together?" The Doctor counts the pile of cash and says "Exactly $1990." "Ah," replies the guy. That explains it...... (wait for it) "I knew I wasn't feeling two grand."
