Two men jailed after a drunken joke ended up leaving a police officer injured have had their sentences cut at the Appeal Court.
Nicholas Read and Jonathon Timms were arrested after a police officer was injured in Daventry on 7 February.
Read, 31, of Riverside Drive, Weedon, Northants, was jailed for 18 months after admitting assault causing ABH.
Timms, 31, of Clover Close, Rugby, Warks, got eight months after admitting assault with intent to resist arrest.
Read was indulging in "drunken stupidity" by following two officers in Daventry town centre, mimicking their walk and "singing the Laurel and Hardy theme tune" at 0230 GMT, when the officers challenged him, the court was told.
An altercation happened during which Read knocked off an officer's hat and was pepper sprayed.
However one of the officers suffered serious knee injuries trying to stop him escaping.
Timms also got one of the officers in a headlock during the scuffle.
The pair were jailed at Warwick Crown Court on 20 August this year.
Lord Justice Gross, Mr Justice Butterfield and Mr Justice Roderick Evans, sitting at London's Criminal Appeal Court, ruled that both men's sentences were "manifestly excessive" and cut them.
Read's sentence was cut to 12 months and Timms was cuts to six months.
The court heard that one officer suffered a fractured kneecap and a ruptured ligament in the melee, after sticking his foot out to stop Read escaping.
