The Big Bang theory

7.00pm rté 2

It seems to have been on our screens for longer than it would take to walk a light year, but all good things must end.

For 11 seasons, we’ve followed the hilarious misadventures of science geniuses and social klutzes Leonard, Sheldon, Raj and Howard.

The 12th and final series begins after the long-awaited nuptials of Sheldon Cooper and Amy Farrah Fowler with their honeymoon in New York. Naturally, nothing goes according to plan.

Leonard and Penny find they have more in common with Amy’s parents than they are comfortable with, and Raj falls out on Twitter with a famous scientist.
