My uncle went with a tour group. Since there were 2 vegetarians, one being my uncle, they had assigned seats together every meal, except when they visited a Buddhist temple and ate at a vegetarian restaurant. The guide mentioned multiple times that morning about the vegetarian restaurant and it’s also listed in the itinerary.

Guide: These 4 tables are all ours, sit where you like.
Uncle: *sits*
Veggie Tourist: *moves to uncle* Hey, why are you sitting there, it doesn’t say veggie.
Uncle: They’re all veggie seats.
Veggie tourist walks off.
Tourist: Hey dude, we’re in a vegetarian restaurant, just sit down anywhere.
Veggie tourist ignores and continues looking.
Uncle: …
Veggie tourist keeps wandering about, ignoring offers to sit by others in the group. He’s still walking around when everyone has claimed a seat.
Guide: Excuse me, sir? Empty seat over there.
Veg tourist: Where are the veggie seats? He *points to uncle* just sat randomly.
Guide: This is a vegetarian restaurant!! Everyone is eating vegetarian here!
Veggie tourist: … Oh. Why didn’t anyone say so?

My husband – then fiancé – and our best friend had apparently found a toy spider on the ground. Knowing that I hated spiders, they thought it would be a good prank to put in passenger car visor, knowing I would sit there.
Time passed and they forgot about it until a few weeks later when my husband and I went out. I pull down the visor and scream in panic as a huge spider falls down. I swap it away and it lands by my husband. It takes him a moment to remember and then he just laughs.

It was really funny. Afterwards.

I work at a locally owned pizzeria. We’re kind of a mess right, as we just got a new owner a few months ago (he isn’t very good). We, sometimes, have canolies (they’re homemade).
A lady called in (a nasty “regular” just trying to get free food) and starts the phone call by asking if we have cannolies. I had to inform her that we, sadly, had no cannolies. Her response (imagine the crabby Spongebob meme) was “How am I supposed to celebrate my 40th birthday??”.
She then “thanked” me for ruining her birthday.
Oh, friends, but story does not end there.
She then calls about 2 hours, happy as a clam.
Talk about odd.
