Chris Tarrant, British radio personality best known for hosting Who Wants to Be a Millionaire, has also appeared in advertisements for Brain Age.

His recent marital infidelities, heavily covered by British paparazzi, have reputedly increased sales drastically for both the DS Lite, and Professor Kawashima's Brain Training: How Old Is Your Brain?

One particular advert depicted Tarrant forgetting his wedding anniversary and getting kicked out by his wife, only to use the game to improve his memory skills. Obviously this particular scenario rang true for countless husbands across the nation, resulting in mass Brain Training to avoid similar marital situations.
