How to Pick Up Girls!

is a 1978 American comedy television film directed by Mick Jackson and Bill Persky, starring Desi Arnaz Jr., Bess Armstrong, and Fred McCarren.

Robby Harrington, (Arnaz) Becker's childhood chum, had been living in New York for years and invites Donald out for a change of pace, and secures him employment and to hone his photography skills with seasoned model photographer Chandler Corey (Richard Dawson).

Co-Producer Alan King makes a cameo as a cabbie Manny Shiller and scares away the thief and bestows some much-needed knowledge to the guileless Becker.

But Becker's swing needs a big push to get off the ground, yet he finds friendship in the company of Sally Claybrook (Armstrong) who is currently in an off-and-on relationship (presently off) with married man Frank Cavanaugh (Rudolph Willrich).

Donald meets Terry (Denise Flamino), a gorgeous young woman in the bar, grips the tape recorder and microphone and tries Claybrook's technique and gets her number.

Unfortunately this confidence ultimately blinds Becker as he swoons Cynthia Miller (Deborah Raffin), an alluring model and girlfriend of his employer (Chandler Cory) of four years.

In the midst of Becker getting more material for his book he sees Claybrook infuriatingly leave the apartment exclaiming, "I'm a failure and a fraud" because the notes for her thesis are just culminating with no signs of fruition.

Donald takes her apartment key from her secret spot (a humble loose bannister knob) and organizes the archives and bestows all the credit to Max, her dog who isn't the best watchdog.

Becker's star keeps climbing as press and beautiful women clamor for him, even the venomous Dana Greenberg sees Donald's book and stardom skyrocket, and decides to gain a reprieve with him.

Soon enough Harrington and Becker's apartment become too crowded with overstock of his book, Donald seeks a more suitable abode to complement his successful jet-set lifestyle and his best friend Robby.

While back at the old apartment Donald stands in the center of a maze of boxes packing his book in envelopes, Sally comes to tell him that she's leaving to Chicago for good with Frank Cavanaugh.
