You can get tested on Monday
Be exposed to covid on Tuesday
Get a negative result on Wednesday
Go out and meet your friends on Thursday
Be mildly symptomatic on Friday
'But I tested negative' you wail
Get tested again on Saturday
And you're positive by Monday.
Solomon Grundy,
Born on a Monday,
Christened on Tuesday,
Married on Wednesday,
Took ill on Thursday,
Grew worse on Friday,
Died on Saturday,
Buried on Sunday.
That was the end,
Of Solomon Grundy.
