Those who complete (compleat!) the Munros can record this fact and receive the magic number by writing in to The Clerk of The List (See here). Additionally, a list of current compleaters is published annually in the SMC Journal.

Ben More (Mull), 15th September 2007
Robert writes: I completed the Munros when I summitted Ben More (Mull) at 9:38 a.m. on Saturday, 15 September 2007. My first one was Ben Lomond (3,195 ft) on 21 July 1996. Thus it has taken me nearly 11 years and 2 months to climb them all. My record number of Munros for one day's climbing is 5. I am 54 years old and was born on 19 March 1953. I had actually started the climb at 6:15 p.m. on Friday, 14 September 2007, and had camped overnight on the mountain at just over 2,000 ft before finishing the climb in the morning. I then descended via the same route and was back at my car at 12:55 p.m. yesterday. I have also climbed all 19 of the other Munro equivalents in England, Wales and Ireland.
