Funny Italian Puns

It was a Roman tick comedy

Hey guys. I need help with a pun, I've been thinking about it for a while and haven't come up with it. In Portuguese you informally say "xau" when you're saying goodbye to someone (sound's almost as the Italian "ciao"). I have a friend who always makes this funny pun when we're going our separate ways, he always says "Xau-sescu" (Ceaușescu - as in the Romanian dictator) and for a few months I've been looking for a nice comeback to that pun. I was looking for a way to incorporate the name of a dictator and the word "goodbye" (in any language possible), but so far I haven't been able to. Could you guys help me out? In my native language, Portuguese, I haven't come up with anything cool (my knowleadge in dictator's names is also not very vast).

Thanks!

The other day we went for pizza and the server asked if we were ready,

Server: what are you having?

Dad: I'll have a calzone, size 40.

Me: ...

the server and my parents start laughing.

Mom: come on son, laugh, that was a funny joke.

Me: no mom. That joke was too cheesy

EDIT: in spanish the word "calzone" translates to "underwear" amirite italians?
