Olympian and celebrity lookalikes! Greg Rutherford and Neil Patrick Harris

We love checking out famous lookalikes, and we know you do too, so here's a special Olympian edition of celebrity lookalikes! When Greg Rutherford won his surprise gold medal for long jump on Super Saturday, we couldn't quite believe how similar he looked to How I Met Your Mother star Neil Patrick Harris. In fact, people on Twitter noticed too as 'Barney' became a trending topic! (NPH's character's name on HIMYM). It's just TOO freaky.
