Family Fortunes/YMMV

"Narrator: Family Fortunes ran for over 20 years with four different hosts: perma-tanned Bob Monkhouse, followed by bumbling Max Bygraves, cheeky scouser Les Dennis and erm ... him."
 * Growing the Beard: Many consider Les Dennis's arrival to be when this happened.
 * Memetic Mutation: The "survey said 0" noise.
 * Replacement Scrappy: Max Bygraves and Andy Collins. Neither was a particularly bad host per se, but they both fell some way short of the standards set by their respective predecessors, Bob Monkhouse and Les Dennis.
 * As seen in this 2005 (pre-Vernon Kay) documentary regarding Andy Collins:


 * They Changed It Now It Sucks:
 * Two examples came from a change in host.
 * When Bob Monkhouse was replaced by Max Bygraves in 1983, the show lost some its popularity and was placed on hiatus in 1985.
 * When Les Dennis was replaced by the comparatively-unknown Andy Collins in 2002, the show moved to being a daily daytime version with a lower budget. Fortunes lasted only a few months before being axed.
 * Another change viewers thought sucked came in 1987, when a new colour LED board replaced the older-style display board; people complained about it, so the old-style board returned in the following series.
 * What an Idiot: Has its own page.
