A quick look at the odds for the weekend if anyone fancies a little gamble on the event

02:00 Chael Sonnen (9/4) v (33) Anderson Silva (2/5)
02:00 Demian Maia (5/4) v (33) Dong Hyun Kim (3/4)
02:00 Tito Ortiz (11/4) v (33) Forrest Griffin (1/3)
23:00 Constantinos Philippou (1/2) Riki Fukuda (24/19)

03:00 Chad Mendes (1/100) Cody McKenzie (33/19)
03:00 Cung Le (11/17) Patrick Cote (1/4)
03:00 Ivan Menjivar (1/100) Mike Easton (1/100)

I don't think I'm understand these odds. For example, how can Menjiar and Easton both be 1/100?

Yeh there are a couple of fights I dont understtand at all. Almost as if the bookies haven't made their mind up yet.

Really surprised at how strong a favourite Paddy has Cote against Le
