Justin Bieber -- 2 Jail Videos + Weed Found in Seized Escalade

Justin Bieber -- I'm A Bad Ass Behind Bars

Justin Bieber had his ass up in the air during his short stint in jail ... impressively doing 23 1/2 pushups in 28 seconds.
The jailhouse video -- obtained by TMZ -- shows Justin in his cell after being busted last month in Miami Beach for DUI and resisting arrest.

It's unclear what possessed him to show off his physical prowess, but he seemed excited about upping his cred.

Law enforcement tells TMZ ... there's one part of the 9 hours of video which shows Justin clearly under the influence. Frankly, we've looked at the video and Justin doesn't seem obviously under the influence ... at all.

Justin Bieber -- Stumbles in DUI Jail Video ... Cops Think It's Smoking Gun

Here it is ... the footage of Justin Bieber in jail last month following his DUI arrest ... the same footage Bieber tried to keep out of the public eye ... but it may actually HELP him.

The video shows Bieber taking a sobriety test while inside the jail facility -- trying to walk a straight line.
Law enforcement sources tell us ... this particular clip is their best evidence Bieber was under the influence -- because he misses a couple steps -- but we gotta be honest ... it's not THAT bad. Watch the video and judge for yourselves.

As we reported, Justin's lawyers tried to block the release of the footage -- after video surfaced of him getting patted down in jail -- but the judge told them to pound sand.

According to the police report -- obtained by TMZ -- after the vehicle was towed to police headquarters it was inspected and cops found pot -- less than an ounce. They also found 2 large glass smoking pipes with weed residue.
