I folded AA preflop

[Shorty35]

Here is how it happened:

$20 stars SNG. blinds 50/100; 7 players; I have about T3000 and second chip position.

EP calls 100 ; mp calls 100, mp+1 raises to 300; I am in cut off and I......

get a phone call.
I answer the phone with the intention of using my time bank to figure out how to milk the most $$$ and, to my surprise, my time bank was already used - and I fold automatically.

I was fortunate enough to come back and win; so it makes for a great story. Any one else with a similar story of near self destruction?

My other common mistake (look out for it) is accidentally typing 753 when I intend to raise 75. I have been burned on more than one occasion with that stupidity..
