Goodbye My Friend Puns

I couldn't believe he would just disappear like that

Him: See ya, Dad!

His Dad: That's spanish for city!

Saying goodbye to my friend I haven't seen in a long time who is now a PA in urology:

Him: If you need any Viagra just let me know!

Me: That's not a problem...yet. Not gone wood! (Sounds like "Knock on wood" when you say it)

We were laughing and hating me at the same time.

I was telling him about how I needed to go say goodbye to a good friend of mine tomorrow. My friend is a new second lieutenant of the US Air Force and he's leaving to go to his assignment soon.

Boss: Hey, how many lieutenants are there in the Air Force?

Me: I don't know. A lot I guess.

Boss: Well, I think it's pretty cool that he came in second.

My groan sounded a lot like laughter.

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!

My parents and a friend were over for dinner. My friend drives a Honda Element. Parents said goodbye and walked out to their car... Dad walks back in and says, "Hey bud. I think you're a little out of your element!" (He walked back in for that joke! Smh)

I was on the phone last night with an old friend from high school, and as we are saying our goodbyes after a decently long conversation, I say,

"Hey before you go, did you hear about that guy who got his whole left side cut off?"

Her: "no..? Oh my god what happened?"

Me: "oh, well he's all right now."

Her: groans "You haven't changed." Hangs up

Not sure if it's exactly a dadjoke, but it gets a groan from everyone I tell it to.
