How do you say 'Have fun' in Latin?

Habeo is the verb for fun so the imperative is habe for singular and habete for pluarl. Fun is ludus. I believe it is second declension which would make is ludi for plural. So you get...

habe lusus=have fun singular nomnative

habete ludi=have fun plural nomnative

The English idiom "have fun" doesn't translate directly into Latin. As in French or Spanish, the best equivalent is an expression that means "amuse yourself": oblecta te(singular); oblectate vos (plural).
