CBS sent a clip about Monday’s primetime special celebrating the record-breaking career of retiring late-night legend, David Letterman: A Life On Television.

Ray Romano, seen in the clip, hosts the 9:30-11 PM program celebrating his more than three decades in television; Letterman’s last night as host of Late Show will be Wednesday, May 20.

Plus I got a haircut,” Drew Barrymore’s girlish desk-top tit flash, and so much more.

Romano reminds viewers  why he’s the perfect host – it was his 1995 stand-up appearance on Letterman’s show that led, one week later, to call offering him a development deal that, in turn led to his CBS comedy series, Everybody Loves Raymond, produced for CBS by Letterman’s Worldwide Pants. Romano will take viewers through the retrospective of Letterman’s career, starting from his time as a weathercaster in Indiana to his final nights as host of the CBS late-night program.

Following the special, CBS announced this morning President Obama will be Dave’s guest on Monday night’s  Late Show .
