Once upon a time, three vampires met in some place at night. Apparently, each one of them was boasting about their vampiric abilities to one another.
Vampire A said, “Look at that mansion over there! I can finish all of its inhabitants within 10 minutes!” And so he flew to the mansion. Nine minutes later, he came back with his mouth filled with blood, looking satisfied with himself.
Vampire B then said, “Bah! Look at that village over there! Give me 5 minutes!” He flew to the village and returned in the next 5 minutes with his mouth filled with dripping red blood.
Vampire C then yelled, “Pffft! Look at the TOWN over there! Give me 3 minutes!” He flew in the direction of the town, and one minute later, he returned with his mouth filled with blood.
Vampire A and B stared at him with amazement, then immediately asked, “How come you have such speed, friend?”
Vampire C pointed in a direction and asked them, “Do you see a building over there?”
“Yes!” answered A and B.
“Well, I DON’T!!!”
