jokes you've made IRL that flopped

[blendedsuit]

Years ago I was visiting CalTech on one of those pre-freshman campus tours. Afterwards the admissions staff sat the 8 of us students around in a circle in a small room. The admissions people are pumping up why everything is so great there. Half way through the presentation they ask if any of us have any of those nerd jokes that you can tell here. Well, after 5 seconds of silence or so I volunteer.

I ask the group:
"Which one of the trigonometric functions is blind?"



Everyone just blankly looks at each other, and I respond,


"The secant."

Man, I couldn't get out of there fast enough.
