Old snake with his CQC skills and IPhone in his pouch along with his cigs and rations calling Otacon....
Snake: "Dammit Otacon, where's the keypad for this thing?"
Doc: "It's a touch screen Snake. Touch the screen for the keys to activate"
Snake: "WTF! Nothing's happening! The colours are all changing when i 'touch' the screen!"
Doc: "Not so hard, Snake. Be gentle"
Snake: "Now there's only smudges and fingerprints all over it! Should've wiped my hands from crawling around so long in the mud before using this thing"
