Click to viewBoomp3.com At a press conference announcing the start of physical production on Sherlock Holmes, Robert Downey Jr. tried his best to get his co-star Rachel McAdams to crack a smile. Downey asked McAdams about the itsy bitsy spider’s journey down the waterspout and how the rain lightly came down on her arm, but still no smile. Not even a smirk. Then Downey Jr. started to softly sing a Beyonce song, but the Mean Girls star remained tight-lipped. As Downey began to search the deep recesses of his mind, he pulled out a fairly recent chestnut. Downey cleared his throat as his face twitched slightly then tilted his head to the side and asked, “Are you going to full retard with your performance? Or half retard?” McAdams’ smile appeared like a rainbow after heavy rainfall and Downey breathed a major sigh of relief. [Photo Credit: Getty Images] *A Call To The Bullpen is a work of fiction.
