A Texas pizza restaurant is closed now due to their employees' food tampering antics. Springtown police say they discovered possible food tampering at Mr. Jim's Pizza after one of their employees posted online about putting laxatives on pizzas. Three of the employees were reportedly found to have put Miralax on a pizza pie eaten by a co-worker, who later got sick, but they deny they tampered with any pizzas purchased by customers. The restaurant's' health permit has been pulled until an inspection takes place next week. Mr. Jim's Pizza says the three "prankster" employees have been fired.
