Cut one lime into wedges and run a wedge along the rim of each glass. Pour the Tajin seasoning onto a flat surface, and press the lime juice-coated rim into the Tajin until it sticks. Set the glasses aside.
In a mixing glass, stir together the Clamato, Worcestershire, soy sauce, hot sauce, and all of the juice from one lime.
Fill the Tajin-rimmed glasses with ice. Pour the Clamato mixture over the ice, about ½ cup per glass.
Top the glasses with beer, filling to about a 1/2-inch below the rim.
Drop the jalapeño slices into the drinks, then add the skewered shrimp and celery. Slice a small slit into the lime and pineapple slices, and attach them to the rim.
