Glee - can someone tell me why Finn thinks he's the father

[Peaceflower]

...when he hasn't had sex with Quinn?

I've recently started watching Glee and am getting hooked! But it's really bugging me how this happened!?

They were in the hot tub snogging and he got a bit too into it IYSWIM. She told him the sperm can swim in hot tubs.

Thank you! Can you remember which episode this was, so I can research this!

think its the Acafella's episode (the one before Single Ladies football team....)

Thank you, will look for this on c4 player. Can't wait for next episode.

Ha ha, yes, bless Finn. Easy on the eye but not so bright! As Kurt mentioned he is the boy who cheats off the girl who thinks that four squared is rainbow! Oh I love this show so much.................
