Murder. Death. Kill.

Nice

Freeze a date and eat it

Make ice cream and eat it.
Ice skating.
Snowball fight.

Depends on the person
If you're near water, I suggest snorkelling or paddle boarding
Aquariums are cool too.
If they're outdoorsy, maybe hiking to a waterfall or something (possibly not good idea if it's a first date though)
Idk, brethilwen has some awesome ideas. I suggest the icecream one, who doesn't love icecream.

Well, my idea of one would be that me and the other person would see how much it would cost to go on a normal date. And instead stay home, close all the windows, get in the most comfortable pajamas, order a bunch of pizza and soda, and take the money that it would of taken to go on the normal date and buy a bunch of games on steam without heavily looking into what it is about and just play them together, and if we got tired of games we would hook a computer up to the television and cuddle while watching a series. And we'd go on until we fell asleep.

I think you should watch a movie, so you have something to talk about later

THEME PARK

MARATHON EVERY MARVEL MOVIE. If they can't do it, they aren't the one for you.
