The fly is the source of infection Some wild guy told me The fly is the source of infection Believe me it's not so The source of infection is you My fly is like glazed bread Fat and glistening My fly is like glazed bread Has a tidy appearance Not like you The source of infection Don't k** flies Don't k** flies Don't k** flies For how long I've fed you With only swearing in response How many flies I've k**ed How many poor ones have gone But you're still alive the source of infection What if, instead of a fly, I slammed you down Slammed down and flicked you with my nail? But I let you live You, the source of infection --------------------------------------------------
