Aha, I never noticed that bike overtaking the car moment!
I also think Allenby is bad looking, but that might be partially due my hair style and colour preference; by comparison when she becomes lisa she looks much better, I by far prefer black hair to blonde and the style is also better.
I also liked the bartender scene, I didn't mind the tuba, and I think many people thought the scene where the various therapists ask columbo for advice was silly, instead I found it funny, they kept dragging him in different rooms!
