How about,


"Caesar had some jam for tea
Brutus 'ad a rat
Caesar sick in omnibus
Brutus sick in hat"

or, more properly

"Caesar adsum iam forte
Brutus aderat
Caesar sic in omnibus
Brutus siccinat"


The closest translation I ever managed was :

"By chance, I, Caesar, have now arrived
Brutus was here before
I, Caesar, am thus concerned in all matters
Brutus being exhausted".


I am not one hundred percent certain about the verb "siccinare". There is an on-line latin dictionary, Little Rome which gives it as "dry, drain, exhaust", but I suspect that it is transitive. (In which case, the last line should read, "Brutus se siccinat" = "Brutus exhausts himself". This spoils the rhyme and English meaning. I suppose we can take the reflexive meaning of the verb for granted if there is no direct object.)
