What are the most unnatural things that happened to you in an interview?

Cleared the written and the tech round and was up for HR.

Interviewer: you got 30 seconds. Tell me 7 different uses of a blank piece of paper.

Me: 1) I'll use it to write my will. 2) I'll use it to write a love letter.
Interviewer: So basically I'll count writing as one use.

Me: alright, so 2) use it to make an origami.
3) use it as a napkin.
4) use it as a plate.
5)use it to change a hot light bulb.
6)lend it someone who needs a paper.
Interviewer: you got 5 secs left.
Me(hurriedly): Use it to roll a joint.

Awkward silence for 5 secs.

Interviewer: welcome aboard. We need you.

Ps: I don't smoke.
