Once after working a 23 hour shift I left a voice mail for the team on the team voice mail box (back when those were a thing) detailing everything I had done then ended it by saying "I love you. Bye. Amen" I still hear about that today.
When we first moved to the states we were still learning english and we had to deliver news papers to make the ends meet. And my oldest brother was delivering and the house owner was out on his porch so my bro was like "Oh crap! What do I say? He's going to say thank you. Do I just say 'No Problem?' Or stick to 'You're welcome'? He kept debating it in his head and when he handed the guy the paper he was like "Thank you" and my bro smiled and said, "Your problem!" then turned and ran away.
