Tinkle is a phone service in Grand Theft Auto IV and Grand Theft Auto V, much like Badger and Whiz. They have advertisments on the in game television and radio, as well as billboards across Liberty City, with a company building in Alderney City, Alderney and Pillbox Hill, Los Santos. The company is possibly based on the U.S. phone company AT&T. The company is suggested to be a long-running organization, as an olden wall-painted advertising in Varsity Heights may be seen depicting the company in its older name, Tinkle Telecom Corp.. The company competes with Whiz Wireless, with Whiz going so far to use the catchphrase "Whiz is stronger than Tinkle". Like Whiz, Tinkle's name is synonymous with urination, with the company using suggestive slogans like "Tinkle in your ear", "Tinkle underwater" and "Tinkle everywhere".
