I lost the race and won a silly booby prize.
booby prize
idiomA prize or status, often unwelcome, awarded as a joke or disincentive to the loser of a contest or for poor performance.
The team finished last in the tournament and received a rubber chicken as a booby prize.
Despite his earnest efforts to win the competition, he was ultimately awarded the booby prize, a humiliating token of his failure that the audience found quite amusing.
