Let's think up some stage names that aspiring professional dancers should avoid at all costs.

Mya Tuleftfeet
Guy van der Plotz
Iva Harrybumskaya
Grace Knott
Hammertoe McGee

Tula Ellice Finklea - that's Cyd Charisse's real name, so it's taken.

The Four Faux Princes of Ballet.
Vladimir Malakhov's French cousin, Jean-Pierre Maladroit, POB.
David Knockney, ROB
Hy Perex-Tensian, Tblisi Muncipal Ballet
Beau Legg, ABT

My last name was no good--Ricketts!--so I had to change it when I danced.

For anyone with even a slight knowledge of modern greek Malakhov's last name sounds uniquely unfortunate

Ray, your name made me think of a clog cancing company which toured internationally to great acclaim in the 30s. Its stars were

Art Thrytis
Sy Attica, and
Arch Less.
