Lenny Dykstra Begs Judge -- PLEASE Let Me Go to Gary Carter's Funeral

Disgraced MLB star Lenny Dykstra desperately wants to attend the Florida funeral of his former NY Mets teammate Gary Carter ... and has filed documents with the judge BEGGING him to travel even though he's currently under house arrest in L.A..

Carter -- who played with Dykstra on the infamous '86 Mets championship team -- passed away last week after battling brain cancer. His funeral is set for later today in Palm Beach Gardens, FL.

Problem for Dykstra ... he's on house arrest for a whole bunch of alleged crimes, including bankruptcy fraud and embezzlement ... and needs a judge's permission if he wants to leave the state.

In the docs, Dykstra notes that he wants to stay until Sunday ... so he can attend an intimate gathering reserved for close friends and family on Saturday.
