Lea Michele + Cory Monteith. 
Look how short she is! :P 

It's like they started dating when she was like, 
"Hey, dude, could you spot me some Skele-Gro?" 
and he was like, 
"I seriously have no idea what you're asking me right now." 
and she was like 
"Sure you don't.  Sure you don't." 
and thought 
'I can wear him down,' 
but in reality he genuinely didn't know what Skele-Gro was 
and he still doesn't because 
– and you heard it hear first, folks – 
<i>Cory Monteith is a muggle!</i> 

As far I know, it's never been confirmed that overconsumption of Skele-Gro can make you taller...  But I guess she isn't about to stop trying.  :P
