Why does the company lacote use the crocodile in their logo?

The alligator that is embroidered on Lacoste tennis shirts comes from the nickname of founder Rene Lacoste. Lacoste was a tennis star in France in the '20s and '30s, and was nicknamed "Le Crocodile". Lacoste wore tennis shirts embroidered with an alligator on the left breast. Lacoste founded La Societe Chemise Lacoste with Andre Gillier in 1933 and the company began manufacturing the tennis shirt that Lacoste designed (because earlier tennis shirts were too uncomfortable) and wore on the tennis courts.
