Adrien Broner says his jail wish was granted ... he DID get letters from pen pals during his 10-day stint behind bars in an Ohio jail -- and says some people even sent him MONEY!
So, how much cash did did he get?? The boxer wouldn't say ... but he was crackin' some X-rated jokes in the process.
In fact, when Broner and his crew left Playhouse nightclub in L.A. Sunday night -- he even joked about the bowling alley beatdown case against him ... but you gotta listen hard to get the joke.
Here's a hint -- when we asked about "PEN PALS" ... Broner answered a question about "PIN PALS" ... saying, "My last PIN PAL pressed charges on me ... get it?!"
TMZ Sports broke the story ... Broner's been accused of beating up and robbing a former bowling buddy after a night of high stakes gambling on the lanes. Broner has denied the allegations.
BONUS -- Broner also told us he has the same jeweler as Fetty Wap ... but insists that's not the only thing they've shared (Hint: it's women).
