A female Cambridge University rowing crew had to chop wood as punishment after one of the team tore up a tree to celebrate a victory.
The female students, who have not been named, were punished for "excessive deforestation" following the May Bumps rowing races.
Their crew was one of six boats punished by officials for bad behaviour during the competition, reports the Daily Telegraph.
The students were handed the punishment of "chopping wood" after one of the crew uprooted most of a tree from the riverbank and carried it back to celebrate her boat's success.
As part of the tradition students break off willow branches and attach them to their heads once they have caught up with or "bumped" a boat in front of them.
Officials said the "punishments" were "minor jokes". Five boats were also fined for using bad language on the River Cam in front of members of the public.
The races follow a format which dates back to the 1820s. Crews line up along the river with just one-and-a-half boat lengths between each of them.
Participants then row frantically in an effort to bump the boat in front of them, without getting bumped from the boat behind.
