Michael David Fisher (born 12 December 1950 in Acton)[1] is a fictional character in the BBC sitcom Only Fools and Horses.

Friendly but dull-witted, Mike was often on the receiving end of Del's shenanigans or attempts to sell his low-quality goods.

Among the goods he bought from Del were a hairdryer that was actually a paint stripper (leaving Mike with severe burns to the head), a malfunctioning deep fryer and a faulty fax machine.

When Kenneth MacDonald died in 2001, writer John Sullivan added a storyline to new episode "If They Could See Us Now", which explained that Mike had been caught up in Del and Rodney's shady financial dealings and attempted to embezzle the brewery in order to cover his losses, for which he was imprisoned.

In the 2015 book He Who Dares, a fictional Del Boy autobiography, it is said that Mike's prison sentence had been reduced and he had retired to the Isle of Wight to write a memoir of his time inside.
