People have shared the most shocking thing they've caught a family member doing.

But we’ve got nothing on the people of Reddit.

Redditors have revealed the most shocking thing they’ve caught a family member doing and, well, prepare yourselves, it’s about to get really, really awkward.

Venus08 says that he caught his brother “booty dancing to the family guy theme.”

And groovinmoleman revealed that his sister had a one night stand while he was asleep in the same bed.

"Anyway, I opened my eyes the morning after a big night out and the first thing I saw was a random guy staring at me. He didn't speak English and at this point I had a million thoughts run through my head, 'had I slept with him last night?' 'Who tf is this guy?' 'Is my sister still here?' 'Am I even in our room?' 'where tf am I??', and then she sits up and goes, 'oh, yeah sorry, we had no where else to do it'."

Mistah-Jay's grandmother tried to rope them into her shoplifting gang: "She was trying to put her items into my messenger bag. No, she didn't have dementia, and no she wasn't poor. She had plenty of money, she just wanted me to help her steal some shit."

While Averysmallmoose's grandma had been living a double life.

"We shall never speak of this again" on This Glorious Mess. 

"Caught grandma walking normal when she thought nobody was home. She was super passive aggressive and always needed special treatment. Couldn't help or do anything around the house. Got home from school early and she was perfectly fine until she saw me."

caribou12 revealed that they caught their step father picking his nose and eating it.

And things got a little bit too close for comfort in picksandchooses' family: "My cousin went to swingers parties 3 times. I know it. I saw her there."

Great Aunt Carol revealed a little to much to FunkyAssJew: "Pooping. This may seem light, but I saw waaaaaay too much of great aunt carol."

And Isthisaweekday saw his dad doing something you never want to see.

"Ugh, I'm so embarrassed to even type this," they wrote "But, I caught my dad masturbating to porn after my mom went to her night job. I was in elementary school and got out of bed to get something to drink and saw my dad sitting on his knees on a towel on the floor and jerking off into a washcloth. I quickly got my drink and when I came out of the kitchen he was back in his robe on the couch and watching TV like nothing has happened. We never talked about it."

meeeerkat567 once caught her brother wearing her underwear and strutting his stuff around the house.

And lydocia inherited more than they expected when they got a second hand phone from their uncle.

"Tons of downloaded clips and a search history full of... "hot naked grandma". I wish I was kidding. Then I realised, my uncle is nearing 60 himself. That's basically just the age category he is in. Good for him."

While Secretly_psycho discovered that their mother might be planning a murder.

"She has a room full of maps of a few buildings, with exit routes, storage rooms, and vent systems of each. Graphs on the feasibility of mustard gas, natural gas, carbon monoxide. Graphs on how sound would travel, if she were to try the shooting method."

What's the weirdest thing you've ever caught a family member doing?
