Yoga and Sensory Deprivation

I met a guy a few months ago while out West Coast Swing dancing who clearly was interested in me but just recently pulled the trigger and asked me out. The following is a portion of the conversation we had about what to do on our date...

Me: Do you like sushi?
WCS Guy: Yes, love it. I was also thinking of inviting you to come to my yoga class with me. (*side note- I think men who do yoga are pussies. I have many guy friends who do yoga, so I'm sure I'm going to get in trouble for saying that)
Me: I don't like yoga.
WCS Guy: Are you sure?
Me: Yes. I once attempted yoga on a beach in Mexico at sunset with a hot Argentinian yoga instructor. I hated it. If I hated it then chances are yoga is not my thing.
WCS Guy: Well ok then. Well, um, how about after dinner we go to this place that has sensory deprivation tanks?
Me: Oh dear...

Seriously? He might as well have just asked me to Fed-Ex him my box.
