"Bring me a coffee, Bashir!"
Bashir brings a cup of coffee after climbing the stairs for twenty minutes, and Chaudhry Sahib asks: "Bashir! It's been seven years. You bring coffee every day by climbing the stairs, even though you are limping, but the coffee has never spilled?"
Bashir shyly replies: "While climbing the stairs, I take a big gulp!"
Chaudhry Sahib, upset, says: "Bashir! Are you engaging in corruption???"
Bashir, panicking, says: "No, Chaudhry Sahib! After climbing the stairs, I pour that gulp back into the cup." 😂😂😂😂
