I have one that says 'Have A Nice Day' on it, but when you lift it up to take a sip, there's a big middle finger being raised on the underside for the person across from you to see 🖕
Interesting. I have a 14-year-old Ozito whipper snipper that still works just fine.
It doesn't get much use these days because our current place needs something heavier-duty, but I beat the crap out of that thing for a decade and it's never missed a beat.
YYYYEEEAHHHHHHHHH!!!!!!
