He must’ve thought they only allowed the really deadly ones on board.
By SEK is standing in the security line at George Bush Intercontinental Airport. Behind him are three young men with shave heads and many muscles.
MARINE #1: Yo! Marines?
MARINE #2: ARE AWESOME!
MARINE #3: Every member of the other armed forces is a giant weeping vagina compared to–
ALL THREE: MARINES!
SEK ascertains that these strapping young men must be Marines. He proceeds through the checkpoint with no problem, so too do the first two MARINES.
TSA AGENT: (to the third MARINE) Sir, can I ask you to step aside?
MARINE #3: (looking perplexed) Me?
TSA AGENT: Yes sir.
The TSA AGENT pulls a Paul Hogan “Now THIS is a knife” from the third MARINE’s carry-on.
MARINE #3: You can’t take that! It’s my graduation blade!
SEK would tell you what happened next, but loitering around security checkpoints while sporting a beard is a bad idea even if you’re a Jew.
