See No Evil, Hear No Evil, Speak No Evil

I'd get rid of taste. Then I could drink all the pro-shakes I want and not gag. It would also make me super healthy.

I was going to say smell, but Momiji the Nerd has persuaded me. Taste it is.

Taste is the most useless one

all I can think about is how much money I'd save/weight I'd lose if I couldn't taste anything

I like my sense of smell more than anything because it is AMAZING (!!)

I'd probably go with smell. I have a friend who lost his sense of smell when he was younger for no apparent reason, and he still tastes things absolutely fine. Taste is more important to me (food!), touch would ruin a lot of things and make others difficult, sight and hearing are both kinda a big deal.

No way would I give up sight.
No way would I give up hearing.
No way would I give up feeling.
So that leaves taste and smell.
But seeing as the question's intent is clearly "Which of your senses do you value least" and not a biology quiz, I'm going to say smell :p Because within the constraints of this hypothetical it's allowable that you would lose one without affecting the other.

Taste. All my other senses are important to me. I couldn't stand the idea of not seeing, smelling, hearing or feeling things.

Though all of the senses are important, I could easily take off the sense of smell as it is of little use to me.
