Toby Leigh said he took great care not to violate any Olympic copyrights when he created the totes, which are modeled on the London 2012 logo but do not contain the word "Olympics" or any associated symbols, The Sun reported Tuesday.
"You can't use the words London 2012 or the Olympic rings, but they can't copyright the word London," Leigh said. "The typeface isn't the same typeface either."
The bag slogans include "They're all on steroids," "I'm renting my flat to fat American family" and "It only took me three hours to get to work this morning."
Leigh said sales have been so brisk the bags have temporarily sold out.
