1) Pat G claimed to have nicked a tube train from Mill Hill East station when he was 14. Swore blind he just jumped into the driver's compartment, shut the door and took the train to Finchley Central, where he was stopped by LU staff turning off the track (and presumably sent on his way with a clip round the ear).
2) When I was 12, this kid called Steve told me he had a 2-year old daughter. He got really pissed off and just glared at me for weeks for the crime of disbelieving him. We did become mates eventually (after a really half-arsed fight after maths), but he used to come out with all this constant crap, like how his uncle had produced 'Dark Side of the Moon', or he was seeing a page 3 model called Leslie who used to let him stay round her flat (he never gave her full name or explained who she was, cos 'I don't want you wanking over her'). Last I heard he was starting a band.
3) I knew a mad girl who claimed she was forced to have an abortion by an abusive ex-partner. Then one day she revealed she couldn't drink vodka shots, because that was how she'd lost the baby. The story used to crop up with depressing regularity, but the details always changed. '****'s baby' became a source of behind-her-back jokes, like, "Oh yeah, that time we got stranded on the moon base, and one of the space pirates shot me with a photon scrambler...and I lost the baby", etc
4) An older relative of mine claimed to have caught a pike in Ireland, using only a hook on a flimsy piece of thread from his shirt. Me and my siblings were informed that if we ever went to a pub in the village and mentioned we were related to the famous guy who caught the pike, we'd get free drinks all night.
5) The following is from a complete nobhead I used to work with - for the record, he was intensely uncomfortable around women, often blamed the fact he was prematurely bald and wore glasses for a lack of female interest and used to come out with the 'why does nobody want a genuine, caring guy' line all the time. Now this is him, upon getting his first ever g/f and having two pints at a Xmas work lunch.
"HEH HEH! YEAH, I'VE DONE MY FAIR SHARE OF FILLING MY BOOTS! I'M LOOKING TO SETTLE DOWN, MY WILD DAYS ARE BEHIND ME! WHAT ABOUT YOU - WHEN ARE YOU GOING TO GET A GIRLFRIEND, MARTIN? HEH HEH!"
Cue looks of WTF around the table. She cheated on him twice and then he went into a sullen "doesn't know what she's missed out on...yup...she'll end up all alone, then she'll realise...". Funnily enough she lost her flat so rang him back up saying, "I've made a big mistake", and he moved her in instantly. Still going, according to a 3rd party source. I also found out that he'd been telling everyone about all these weird, wacky things he'd seen when he went to Japan. I was really impressed cos they were all things, almost word for word, that I'd told him about from the time I went.
6) I once told a girlfriend I could speak French (she couldn't). She'd be like, "It's really sexy, just talk in French", so I'd be whispering all this shite like "le jambon et le tapis dans la boucherie, ce soir je voudrais un syndicat d'initiative" in her ear. She went mental when I told her the truth, years later.
I've seen bullshitology, alright.
