I'm there almost ready to stab a heavy and his medic ubercharges him. Yes I know I'm supposed to go for Medic first but for some reason I like to kill Heavy first, look at the dead Heavy's Medic and do one of these:
(1) if time allows: (a) disguise as enemy heavy while nearby that medic (b) call for medic using the "medic" command (c) run away
(2) if time is short: (a) look at medic (b) do a disgrace taunt (c) run away
(3) do a combination of (1) and (2) or a brief version of (1) and (2)
