thumb|The "Give Peas a chance" graffiti on the Chalfont Viaduct, before its removal in 2018 A piece of graffiti on the Chalfont Viaduct, clearly visible from the M25 and reading "Give Peas a chance" (parodying John Lennon's "Give Peace a Chance") became popular with the public, attracting its own Facebook group. The message originally read "Peas", supposedly the tag of a London graffiti artist; the rest of the wording is reported to have referred to his frequent clashes with the law. In September 2018, after almost 20 years, the graffiti was vandalised and then removed and replaced with the message "Give Helch a break". A spokesman for Network Rail sympathised with the requests to restore the "much-loved graffiti", but said they do not condone people putting their lives at risk by trespassing.
