When the penny drops!
You might be familiar with the BBC quiz show Letterbox, it's a game that involves contestants picking letters to form a word.
Essentially, it's like a game of hangman where the contestants have to guess a fictional character.
On this edition of the show, Lyndsey started well as she correctly guessed some of the vowels and consonants that formed the name, but as she cleared the remaining slots, she became stuck.
After handing over to Troy, he managed to clear the board a bit more but then the real comedy kicked in.
Take a look as both contestants can't answer a problem that everyone knows.
The reactions in the background - along with that that moment when the penny drops - are bound to make you laugh!
