The tooth phone would be annoying, mainly because I love to text. Plus, I don't want to hear someone breathing like a creep. I guess I'd either like to see the Coke Burn or Fido Fusion just because those sound awesome.
Kids these days. My little brother and I were playing PS2 and he said "I'm horny" to me. I was like "WHAT?!". I asked him what he thought that meant and he told me that his friend said it meant that his balls itched.
