I will send u a $20 (American) gift card to ya if you can correctly answer this ? So you obviously know i officiate football....LOL I have a piece of equipment known as "The Clip" that i use. I only use it when i am the head linesman, when i have the "Yard-to-Gain" crew. The clip is placed at the nearest 5-yard line at the start of every offensive series. The clip is used in case there's a play that runs out of bounds at the chain crew. We then re-set the chains via the clip by setting it at the 5 yard line it was at. Said "clip" has all the 5-yard lines on it 5, 10, 15 etc. Why then is there a 55 yard line on the clip? (Being that a football field is only 100 yards.) Answer that and i will personally send u a 20 dollar petco gift card! (Only the first to answer correctly tho!)
