In a small bowl, combine the lemon juice, Tabasco, and Worcestershire sauce. Set aside.
Heat 4 tablespoons of the butter in a large skillet over medium-high heat until melted and foamy.
Add the shrimp in a single layer and sprinkle evenly with the Old Bay seasoning. Sauté, turning once or twice, until the shrimp are pink, opaque, and just cooked through, about 3 minutes total.
Add the lemon juice mixture, thyme leaves, and remaining tablespoon of butter. Toss until the butter melts and the shrimp are evenly coated in the pan sauce.
Season to taste with freshly ground black pepper, remove from the heat, and serve immediately with the pan juices spooned over the top.
