Wrap shrimp (from back to front, then around) with 1/3 of uncooked bacon slice; lay flat on medium-high heat griddle.
Cook, turning occasionally until bacon is brown (but not crisp). Lay pineapple chunks on griddle for 2½ minutes, turn once, and grill another 2½ minutes.
With toothpick, skewer cubes of pineapple, then bacon/shrimp combinations. Place finished shrimp kabobs on plate and serve immediately.
