how does everybody else deal with this classic situation:

you've worked around these guys for 30 years... so you KNOW them, right?? Yet, when you pass one of them on the way to the coffee machine , his name just won't pop into your mind. He greets you by name. What do you say in return?

Everything *I* can think of is pretty lame.


"Heyyyy, how's it goin'?" (lame)
"Duuuuude!" (extra lame with a side order of cheesy)
just nod, smile and don't say anything (dead giveaway)
