"I love my brick!"

Jack and his brick. (Speed 3)

Brick is Father Jack's very own pet brick which he lovingly cares for, only to have a sudden change of heart and hurl it at Ted.

Ted then gets the idea to use said brick in order to save Dougal's life after Pat Mustard has placed a bomb on the milk float as revenge for Ted getting him fired after he is photographed leaving the houses of several female customers on the island, clearly having had sex with them.
