No one will ever find out.
Sheldon introduces himself as Skippy Cavanaugh, a wedding planner who cant find love.
Both are unwilling to make the first exchange.
What if Leonard gives the guy the money and he drives away?
What if the guy gives them the helium and they dive away?
The helium guy notes that they have reached a stalemate.
Sheldon schools the helium guy on the proper use of the word stalemate.
This morphs into a dazzling conversation dissecting the difference between reaching an impasse and a Mexican standoff.
Meet Kenneth Fitzgerald (played by the wonderful Michael Rapaport).
Skippy demands that Kenneth give them the helium, or he will turn Kenneth into the authorities.
Its a perfect example of how a Mexican standoff works.
Sheldon congratulates him on another great example.
