From Charlie Randall's cricket site:
"Peter Roebuck, Somerset’s captain, complained about Hampshire’s runner during a NatWest Trophy match at Southampton in 1988, holding up play with protests that Paul Terry was exceptionally quick and much faster than the injured batsman Chris Smith could ever have been. Umpires Jack Bond and Ray Julian calmly informed Roebuck that the Law on runners did not specify speed.In 1994 Warwickshire sent out the heavyweight Andy Moles, already tired from his own innings, to assist Brian Lara at Scarborough as a humorous protest against the West Indian’s request for a runner."
