Ha ha! Yeah, Dr. S, it's not a great visual in my mind, either. I think you might get a kick out of this, though... When we were all waiting for his arrival to do the shoot at the club, the DJ brilliantly had him set up. When DVD walked in, the DJ surprised him as he got on his mic and announced "Ladies and Gentlemen, please welcome Mr Dick Van Dyke!" then promptly put on a record of the DICK VAN DYKE SHOW theme. Well, Dick didn't miss a beat and arched his shoulders back and came bustling in the place, waving at us all - then did a mock trip, right on the music cue! Of course, we all busted up and applauded his improv. THAT was a cool thing to see!
There is a YouTube video show many of the takes needed to get the trip right. He tripped over and over again. The one where he sidesteps the Ottoman was improvised and was used later.
Also, Dick Van Dyke did a video on driver safety 60 years ago after a accident where he hit a wall at 50 mph. Lap belt saved him. He hasn’t learned yet!
