Tofu - The other white-ish non-meat substance of some sort

What you may have overheard during lunch with my dad:

Me - Have you ever had tofu?
Dad - I think I did once, but I got better, so it must have just been a virus.

That put me down for a good two minutes. Obviously he was joking. My dad can be hilarious, as my friends can attest to. Sometimes it's even on purpose.
