While waiting to enter the taxiway in ONT, (California) an Airbus working for a major parcel carrier came face to face with our corporate 727 and the following conversation ensued:

ONT Twr: Airbus 1234, where are you going today, sir?

Airbus 1234: Right where that 727 is, and, uh, be advised our tail might be a little bit over your runway.

Boeing NABC: Don't worry. A little tail never hurt anybody.

(awkward silence)

Airbus 1234: ... Wish I could say that.
