Wale -- Jerry Seinfeld's My Boy, But He Don't Know Crap About Rap

Jerry Seinfeld can team up with Wale to make hysterical skits -- but the rapper tells us there is a limit to Seinfeld's talent in the entertainment biz.

If you haven't seen 'em ... Wale and Seinfeld are like a new odd couple in a series of online vignettes -- and our guy asked Wale about the one where Jerry tells him how to rip music critics who left him off a "best of" list.

Wale gives JS major props for the comedy -- but you gotta see how his tone changes when we ask if Jerry's gonna help him record new music. Wale doesn't want to say it, but he's saying it: Stay in your lane, Seinfeld!

Something tells us Seinfeld (and the world) will be fine if Jerry doesn't rap.
